enhancements that ensure fail-safe embedded system operation and application versatility are a
watchdog timer, a powerfail NMI generator, serial console support, serial boot loader, non-battery
boot, failsafe boot, accelerated boot, on-board high-density CompactFlash disk, and BIOS extensions
for OEM boot customization.
System operation requires a single +5 Volt power source (and 3.3 Volts for low-voltage PCI
expansion cards, if required) and offers "green PC" power-saving modes under support of Advanced
Power Management (APM) BIOS functions.
Product Feature Summary
CPU/Motherboard
The Little Board P6d module has a fully compatible PC architecture, with a Pentium-II low-voltage
CPU.
For improved reliability in harsh thermal environments, the board implements a CPU thermal
sensor and configurable thermal-management control logic in the BIOS.
1-1
The board uses a single 3.3V DIMM memory module for main DRAM memory, and supports from
32MB to 256MB in a 64-bit or 72-bit (ECC) configuration.
The module has a full complement of standard PCI PC/AT architectural features, including DMA
channels, interrupt controllers, real-time clock, and timer counters.
Enhanced Embedded-PC BIOS
One of the most valuable features of the Little Board P6d module is its enhanced embedded-PC
BIOS, which includes an extensive set of functions that meet the unique requirements of embedded-
system applications. These enhancements include:
!
CompactFlash support. You can use a solid-state CompactFlash memory module in place of a
rotating media drive (see CompactFlash Disk, below).
!
Watchdog timer. The WDT monitors the boot process and can be integrated into application
programs using function calls provided in the BIOS.
!
!
Fast boot operation. Normal or accelerated POST.
Fail-safe boot support. Intelligently retries boot devices (configured in the BIOS) until a
successful boot.
!
Battery-free boot support. Saves system Setup information in non-volatile EEPROM. The
board can use this information should the RTC battery fail.
!
!
!
Serial console option. Let's you use a serial device, such as an ASCII serial terminal, as console.
Serial loader option. Supports loading boot code from an external serial source.
EEPROM access function. 256 bits of serial EEPROM storage are available to the user, useful
for serialization, copy protection, security, etc.
!
OEM customization hooks. The module can execute custom code prior to system boot via ROM
extensions; allows sophisticated system customization without BIOS modification.
Modular PC/104-Plus Expansion Bus
The Little Board P6d module provides a PC/104-Plus expansion bus for additional system functions.
This bus offers compact, self-stacking, modular expandability. It is an embedded system version of
the signal set provided on a desktop PC's ISA bus. The PC/104-Plus bus includes this signal set,
and in addition, signals implementing a PCI bus, available on an additional 120-pin PCI bus
connector.
The Little Board P6d module's on-board EIDE, Ethernet, and Audio interface are internally
connected to its PCI bus. In addition, you can attach PCI peripherals to the board's stackable PCI
bus expansion connector in much the same way PC/104 modules are stacked on the PC/104
connectors. The PCI expansion connector consists of 4 rows of 30 pins (120-pin header), and carries
all of the appropriate PCI signals to accommodate up to 4 PCI add-on modules. The bus operates at
clock speeds up to 33MHz.
CompactFlash Disk
The CompactFlash interface allows you to substitute solid-state Flash memory for a conventional
Hard drive. Any DOS-based application, including the operating system, utilities, drivers, and
application programs, can easily be run from the CompactFlash device without modification.
1-2
Little Board P6d Module
The CompactFlash disk is a solid-state or rotating media disk system that emulates an IDE drive.
It uses standard CompactFlash disk media, similar to a PCMCIA memory card, but smaller. Insert
the CompactFlash disk media in the on-board CompactFlash socket, and use it in much the same
way you would use a removable-media hard drive. The CompactFlash drive is architecturally
equivalent to an IDE drive in your system. When installed, it becomes one of the two IDE drives
supported by the primary EIDE disk controller. It can be configured as either an IDE master or
slave drive.
Serial Ports
The Little Board P6d module provides four RS232C serial ports, implemented using 16C550-type
UARTs. These UARTs are equipped with 16-byte FIFO buffers to improve throughput.
Serial ports 1 & 2 have full modem support. There are RS232 level shifters on all signals. The RX
and TX data signals can also be configured as RS485/RS422. The TTL versions of the TX and RX
signals for port 1, 3, and 4 are also brought out to the utility connector. Port 2 TTL TX and RX are
brought out to the Utility connector via the IrDA interface.
Parallel Port
An enhanced bidirectional parallel port interface conforms to the IEEE-1284 standard. It provides
features attractive to embedded system designers, including increased speed, an internal FIFO
buffer, and DMA transfer capability.
Floppy Interface
An on-board floppy disk interface provides access to standard floppy drives. The interface supports
two floppy drives, 5-1/4 inch or 3-1/2 inch. All standard floppy drive types, from 360K at 5-1/4 inch
to 1.44M at 3-1/2 inch are supported.
PCI-Bus EIDE Interfaces
On-board PCI EIDE/Ultra DMA/33 interfaces provide high-speed hard disk, IDE CD-ROM drive,
and other IDE device access. The interfaces support up to four IDE devices (via primary and
secondary drive interfaces). The interfaces are fully compliant with the AS/NSIS ATA Rev. 3.0
specification and the ATAPI Specification.
The CompactFlash interface is implemented as an IDE drive. If it is installed, it takes the position
of one of the drives of the primary IDE interface (settable as a master or slave drive).
PCI Audio Interface
The SoundBlaster™ compatible audio interface is implemented using a combination of the Trident
4DWAVE-NX PCI DirectSound Accelerator, the National LM4549 AD97 CODEC and a National
LM4863 Audio Amplifier.
1-3
Flat Panel/CRT Display Controller
A 69030 video display controller supports both flat panels and CRTs, and offers full software
compatibility with all popular PC video standards (VGA, Super VGA, and VESA). All standard
resolutions up to 1600x1200 pixels at 64K colors for CRTs and up to 1280x1024 pixels at 16.7M
colors for flat panels are supported. 4MB of SDRAM are provided as standard video memory. The
display controller features are:
!
Enhanced AGP Bus Interface – The video controller provides a 66MHz AGP-bus path between
the CPU and the controller.
!
!
Full IBM VGA compatibility – VESA DPMS and DCC standards supported.
Color Flat Panel Support – Up to 16.7 million colors can be displayed on color TFT LCD flat
panels and color STN LCD panels.
!
Dual Independent Displays – The controller provides three different modes, which include two
completely separate and independent video displays (CRT and flat panel) with resolutions up to
1280x1024 at 256 colors at 60Hz.
–
–
–
Dual-Pipe Simultaneous Mode – This mode provides the same image on both displays and each
display (CRT or flat panel) can operate at its optimum timing.
Dual-Pipe Mosaic Mode – This mode provides two displays with completely different images on
each display and each display can be configured at its optimum resolution/timing.
Virtual Desktop Mode – This mode provides a single image or desktop spanned across the two
displays.
!
!
Automatic Power Sequencing Controls. The video controller provides the signals to safely
sequence the power and data signals to LCD flat panels.
Low-Power Modes. The Advanced Power Management (APM) and Advanced Configuration and
Power Management Interface (ACPI) compliant features are implemented in the power control
logic.
!
ZV Port Support. The standard ZV input port for PCMCIA is supported.
100 MBps Ethernet LAN Interface
The Ethernet subsystem is based on the Intel 82559ER 10/100BaseT PCI Ethernet Controller. It
fully supports IEEE 802.3 Ethernet standards - 10BaseT and 100BaseT. Features of this Ethernet
controller include:
!

Little Board P6d Module
Enhanced Reliability
Reliability is especially important in embedded computer systems. Ampro, specializing in
embedded system computers and peripherals, knows that embedded systems must be able to run
reliably in rugged, hostile, and mission-critical environments without operator intervention. Over
the years, Ampro has evolved system designs and a comprehensive testing program to ensure a
reliable and stable system for harsh and demanding applications. These include:
ISO 9001 Manufacturing. Ampro is a certified ISO 9001 vendor. Knowing that many embedded
systems must qualify under EMC emissions and susceptibility testing, Ampro designs boards with
careful attention to EMI issues.
Wide-range temperature testing. Ampro Engineering qualifies all of its designs by extensive
thermal and voltage margin testing.
Shock and Vibration Testing. Ampro products are intended for use in harsh environments and
are designed for shock and vibration durability to MIL-STD 202F, Method 213-I, Condition A
(three 50G shocks in each axis) and MIL-STD 202F, Method 214A, Table 214-I, Condition D (11.95B
random vibration, 100 Hz to 1000 Hz).
Software
The vast array of commercial and public-domain software for the IBM PC and PC/AT is usable in
LB/P6d-based systems. You can use the most popular software development tools (editors,
compilers, debuggers, etc.) for developing code for your application. With this software and the
standard Ampro-supplied utilities and drivers, you can quickly tailor a system to your needs.
Use the board's Setup function for all system configurations. Setup information is stored in both
the battery-backed CMOS RAM-portion of the real-time clock, and in a configuration EEPROM.
Setup information is retained in the EEPROM even if the real-time clock battery loses power,
ensuring reliable start-up.
Setup can be invoked by pressing the DEL key during the Power-On Self Test (POST). The
contents of the EEPROM can be written and read from the DOS command line using a utility
program, SETCMOS.EXE, available on the Little Board P6d Utilities diskette.
Designing Little Board Systems
The board affords a great deal of flexibility in system design. You can build a system using only the
Little Board, serial or parallel devices for input/output, and a solid-state disk drive.
On-board MiniModule Expansion
The simplest way to expand a Little Board system is with self-stacking Ampro MiniModules.
MiniModules are available for a wide variety of functions. You can stack the MiniModules on the
Little Board and avoid the need for bus cables, card cages, and backplanes. For detailed
information, see page 2-43.
1-5
Little Board Development Platform And QuickStart Kit
To help developers quickly assemble an embedded system, Ampro offers the Little Board
Development Platform. It includes a power supply, 3-1/2 inch 1.44M floppy disk drive, IDE hard
drive, CD ROM drive, speaker, I/O connectors, a backplane for ISA and PCI expansion cards, an I/O
development board (described below), and mounting studs for the Little Board.
The Development Platform provides a "known good" environment for your development work. You
can install the Little Board P6d module, MiniModules, or conventional expansion boards, keyboard,
monitor, and I/O devices to quickly create a platform for your hardware and software engineering
needs.
The QuickStart Kit includes cables, documentation, and software needed to develop an application
with the Little Board. Unlike the Development Platform, you must supply the disk drives and
power supply. Technical drawings for the cables provided in the QuickStart Kit are included in
Appendix B.
There are other kits available from Ampro to aid in the development of your application. A Cable
Kit that includes only the Little Board P6d cable set is available.
To facilitate connections to the Little Board P6d utility connectors, Ampro provides the Little Board
P6d Utility I/O Development Board. Figure 1-1 is an illustration of the I/O Development board
showing the connectors and switches that are provided. It is included in the Development Platform

Most I/O connectors are shrouded dual-row male headers for use with flat ribbon (IDC) female
connectors and ribbon cable.
Note
Ampro recommends using “center-bump polarized” connectors to
prevent accidentally installing cables backwards.
You can also design a PC board assembly, made with female connectors in the same relative
positions as the Little Board’s connectors, to eliminate cables, meet packaging requirements, add
EMI filtering, or customize your installation in other ways. Precise dimensions for locating
connectors are provided in Figure 2-1.
The ISA portion of the PC/104-Plus bus appears on connector J1A, J1B, J2C, and J2D. You can
expand the system with on-board MiniModule products or other PC/104-compliant expansion
modules. These modules stack directly on the connectors, or use conventional or custom expansion
hardware, including solutions available from Ampro.
The PCI portion of the PC/104-Plus expansion bus appears on connector J3. It uses a 2 mm 4-row
connector called out in the PC/104-Plus draft specification. Like the J1, J2 connector, J3 has both
male and female connections, allowing for “stackthrough” assembly.

Jumper Summary
Ampro installs option jumpers in default positions so that in most cases the Little Board P6d
module requires no special jumpering for standard AT operation. You can connect the power and
peripherals and operate it immediately.
Jumper-pin arrays are designated W1, W2, and so forth. Jumper pins are spaced 2 mm apart. A
square solder pad identifies pin 1 of each jumper array. Table 2-2 is a summary of jumper use.
Factory settings are shown in the Default column. Some jumpers are set at the factory to configure
options that are not user-settable. These are indicated in the table. Do not change these settings.

Power Requirements
The Little Board P6d module requires only +5VDC (±5%) for operation. The voltage required for
the RS232 ports is generated on-board from the +5VDC supply. An on-board low-voltage power
supply circuit provides power to low-voltage CPUs and certain other on-board components.
The exact power requirement of the Little Board P6d system depends on several factors, including
the CPU speed, the peripheral connections, and which, if any, MiniModule products or other
expansion boards are attached. For example, the keyboard draws its power from the board, and
there can be some loading from the serial, parallel, and other peripheral ports. Consult the
specifications in Chapter 3 for the basic power requirements of your model.
Other Voltages
There may be a requirement for an external +12 volt supply, depending on what peripherals you
connect to the Little Board system. For instance, +12V is required for most flat panel backlight
power supplies. You can connect a +12V supply to the Little Board module through the power
connector, J10. This will supply +12V to the ISA and PCI portions of the PC/104 expansion busses.
Similarly, you can connect -12V and -5V to the Utility Connector, to supply those voltages to both
expansion busses. Pinouts for the Utility Connector are provided in Table 2-4.
2-7
If a PCI expansion card requiring 3.3V is installed, that voltage can be connected to J10-5 to supply
power to J3, the PCI bus interface connector.
Switching Power Supplies
If you use a switching power supply, be sure it regulates properly with the load your system draws.
Some switching power supplies do not regulate properly unless they are loaded to some minimum
value. If this is the case with your supply, consult the manufacturer about additional loading, or
use another supply or another type of power source (such as a linear supply, batteries, etc.). The
minimum power for the Little Board P6d system appears in the power specifications in Chapter 1.
Powerfail NMI
The Little Board P6d module includes a circuit that can sense a power failure. If the +5V power
supply falls below ~4.7V, the powerfail logic produces a non-maskable interrupt (NMI).
When a NMI occurs, the BIOS detects the NMI and displays the message “Power Fail NMI” on the
console. At this point you have two options via the keyboard. You can mask the NMI and continue
(the PC architecture provides a mask bit for the non-maskable interrupt), or reboot the system.
If you want your system to respond to the NMI, you can provide a NMI handler in your application,
and patch the NMI interrupt vector address to point to your routine.
Backup Battery
The Real-Time Clock Battery on the Little Board P6d module should last 10 years under normal
usage.
Cooling Requirements
The Pentium-II CPU, DRAM module, video controller, and core logic chips draw most of the power
and generate most of the heat. The board is designed to support various speed versions of the
Pentium-II from 333MHz to 366MHz with a 66MHz clock speed.
A heat sink and fan are provided for the CPU and a thermal sensor is used to monitor the CPU
temperature, as described below.
Thermal Sensor
A thermal sensor monitors the internal temperature of the Pentium-II CPU. If the thermal sensor
detects the CPU temperature has exceeded its upper temperature threshold (100°C/212°F), the
thermal sensor’s logic sends a signal to the BIOS to reduce the CPU clock speed. This speed
reduction remains in effect until the processor has cooled to the lower sensor limit. Choosing to
operate the CPU at a temperature higher than this upper limit should be avoided due to the
possibility of CPU damage and its erratic operating speed.

System Memory
The module supports a single 168-pin DIMM socket. The system supports both 64-bit SDRAM and
72-bit SDRAM. The 72-bit SDRAM is used to support ECC (Error Detection And Correction). You
can install from 32MB to 256MB, depending on your memory needs.
The ROM BIOS automatically detects the size of the installed memory module and configures the
system accordingly at boot time (No jumpering or manual configuration is required.). The amount
of memory the BIOS measures can be displayed by running Setup. Memory error correction (ECC)
is supported by the chip set used on the Little Board P6d module. DRAM memory is allocated in
the system as shown in Table 2-6.

ROM BIOS
The standard BIOS is installed in a 256KB Flash device at the factory. The top 128KB of the Flash
device is reserved for the system BIOS, located at 000E0000h – 000FFFFFh and mirrored at the top
of the memory address space. The remaining 128KB are mapped only to the top of memory.
A utility program, PGM6X.COM, can be used to program the on-board Flash device. It can be used
to update the system BIOS, video BIOS, or user area. The utility is included on the utility diskette
that accompanies the Ampro Development Platform. The diskette includes documentation about
how to use the program.
Shadowing
To improve system performance, the contents of the ROM BIOS and video BIOS are copied into
DRAM for execution (“shadowed”), where they are accessed as 64-bit wide data. Shadowing a BIOS
ROM substantially enhances system performance. Shadowing for both the ROM and video BIOS is
built into the Ampro Extended BIOS. There is no user setting.
BIOS Recovery
If the BIOS Flash device somehow becomes corrupted, the Little Board P6d system may not boot.
In this case, the BIOS will have to be reprogrammed. A disk with an image of the current BIOS
along with the Utility PGM6X.COM may be used to restore the BIOS image. Before this can be
done, the Little Board P6d system needs to be Booted and running DOS.
Interrupt and DMA Channel Usage
The PC architecture provides several interrupt and DMA control signals. When you expand the
system through the ISA portion of the PC/104-Plus bus with MiniModule products or plug-in cards
that require either interrupt or DMA support, you must select which interrupt or DMA channel to
use. Typically this involves switches or jumpers on the expansion module. In most cases, these are
not shared resources. It is important that you configure the new module to use an interrupt or
2-10
Little Board P6d Module
DMA channel not already in use. For your convenience, Table 2-7 and Table 2-8 provide a summary
of the normal interrupt and DMA channel assignments on the Little Board P6d module.
The PCI bus uses four interrupts (INTA*, INTB*, INTC*, and INTD*). These interrupts are
mapped to any of the available ISA interrupts by the BIOS. If an expansion card has multiple
functions, then more interrupts may be required. You can set the priority in which interrupts are
assigned on Setup 6 — PCI Configuration Setup.

Battery-Backed Clock
An AT-compatible battery-backed real-time clock (with CMOS RAM) is standard on the Little Board
P6d module. A 3.0 volt Lithium battery soldered to the board powers the clock. Battery drain for
the clock is less than 0.4 uA. This battery will support the clock for more than 10 years of normal
usage.
The factory initializes the real-time clock and various parameters in the configuration memory for a
standard configuration. The factory sets the date and time, but it may not be set for your time
zone. Use Setup to change these values as needed.
The contents of the configuration memory are also stored in an on-board EEPROM. The ROM BIOS
reads the EEPROM to get configuration information if the CMOS RAM data is lost. This means the
board will function if the battery fails.
Note
The real-time clock date and time will not be correct without a
battery, or after the battery fails.
Serial Ports
The Little Board P6d module provides four RS232C serial ports, Serial 1 and Serial 2 at J8, and
Serial 3 and Serial 4 at J11.
Serial 1 and Serial 2 have full modem support. Serial 3 and Serial 4 support only RXD, TXD, RTS,
CTS. All ports support software selectable standard baud rates up to 115.2Kbps, 5-8 data bits, and
1, 1.5, or 2 stop bits.
Note
The IEEE RS232C specification limits the serial port to 19.2Kbps on
cables up to 50 feet in length.
2-12
Little Board P6d Module
I/O Addresses and Interrupt Assignments
The serial ports appear at the standard port addresses as shown in Table 2-9. Each serial port can
be independently disabled using the Setup function, freeing its I/O addresses for use by other
devices installed on the PC/104 and PCI expansion buses. When a serial port is disabled, its I/O
addresses and IRQ are available to other peripherals installed on the PC/104 expansion bus. You
can disable any of the serial ports using Setup.
Table 2-9 also shows the IRQs assigned to each serial port.
Note
Serial 3 and Serial 4 ports may use interrupts IRQ10 (PCI) and IRQ12
(PS/2 Mouse), but these IRQs can only be allotted to one device or port
at a time. For example, if you are using IRQ10 for a Serial Port 3 and
also have it assigned to the PCI bus, the serial interrupt will not
occur. You may disable the PCI slot or PS/2 Mouse, to free the IRQ.

ROM-BIOS Installation of the Serial Ports
Normally, the ROM BIOS supports Serial 1 as the DOS COM1 device, Serial 2 as the DOS COM2
device, and so on. If you desire a serial port, and there is no substitute serial port in the system,
then the ROM-BIOS assigns the COMn designations in sequence as it finds the serial ports,
starting from the primary serial port and searching to the last one, Serial 4. Thus, for example, if
Serial 1 and Serial 3 are disabled, the ROM-BIOS assigns COM1 to Serial 2 and COM2 to Serial 4.
Serial Port Connectors (J8, J11)
Serial 1 and Serial 2 appear on connector J8; Serial 3 and Serial 4 appear on connector J11. Table
2-10 gives the connector pinout and signal definitions for J8 and J11. Table 2-11 gives the
RS485/RS422 serial port connections.
The table also indicates the pins to which each signal is wired for compatibility with DB25 and DB9
connectors. The serial port pinout is arranged so that you can use a flat ribbon cable between the
header and a standard DB9 connector. Split a 20-wire ribbon cable into two 10-wire sections, each
one going to a DB9 connector. Normally PC serial ports use male DB connectors. Table 2-12 shows
the manufacturer’s part number for mating connectors.
The RS485/RS422 interface requires that the receiving end of the twisted-pair cable be terminated
with 100 ohm resistors. You can terminate the RS485 interface with a resistor provided on the
Little Board P6d module. To terminate the line, install a jumper on W4-W7, as shown in Table 2-13
.

Ampro Custom Serial Features
The Ampro extended BIOS provides custom serial port features useful in embedded applications.
The serial console feature enables you to operate the Little Board P6d system from a standard
ASCII terminal, replacing the standard keyboard and display devices. See Serial Console Features,
below, for a description of the serial console capabilities.
The serial boot facility enables the Little Board P6d system to boot from code downloaded through a
serial port in a manner similar to booting from a local hard disk or from a network.
The serial download feature permits updating the OEM Flash memory device over a serial port.
Refer to Ampro Application Note AAN-9403 for a complete description of these features. Refer to
the Ampro Common Utilities manual for descriptions of SERLOAD and SERPROG, utility programs
used to support serial booting and serial downloading.
Serial Console Features
You can connect a device, such as an ASCII video terminal or PC running a video terminal
emulation program, to either serial port to act as your system console. To use the serial console
features, connect a serial console device to Serial 1 or Serial 2. Use Setup to enable the serial
console feature. When enabled, the serial console is set up for:
2-15
!
!
!
!
9600 baud
No parity
8 bits
One stop bit
To use an ASCII terminal as the console device for your system, set the serial baud rate, parity,
data length, and stop bits of the terminal to match the serial console settings. For proper display of
Setup and POST messages from the BIOS, you must use an IEEE-compatible terminal or terminal
emulation program that implements the standard ASCII cursor commands. The required
commands and their hexadecimal codes are listed in Table 2-14.
Some Programs that emulate an ASCII terminal do not properly support the basic ASCII command
functions shown in Table 2-14. Ampro provides a suitable PC terminal emulator program,
TVTERM, on the Common Utilities diskette.
After booting this system, the keyboard and screen of the serial terminal become the system
console.
Note
The programs you execute via the serial terminal must use ROM
BIOS video functions (rather than direct screen addressing) for the
display I/O. Some programs that emulate an ASCII terminal do not
properly support the basic ASCII command functions shown in Table
2-14. Ampro provides a suitable PC terminal emulator program,
TVTERM, on the Common Utilities diskette.
After booting this system, the keyboard and screen of the serial terminal become the system
console. The programs you execute via the serial terminal must use ROM BIOS video functions
(rather than direct screen addressing) for the display I/O.
Note
DOS programs that write directly to video RAM will not display
properly on a serial console device.

Using Arrow Keys During Setup
During Setup, the serial console arrow keys and function keys must be simulated. To simulate the
function keys, enter two keystrokes, an “F” followed by the function key number. Thus, function
key F3 is simulated with the literal “F3” typed on the keyboard. (Don’t type the quotes). F10 is
simulated with “F0”.
Note
The keystroke simulations are only valid during Setup, not during
normal operation. The arrow keys are simulated with the substitute
keystrokes shown in Table 2-15.

COM Port Table
When the system boots under DOS, the serial ports are initialized to 9600 baud (typical). To
preserve the selected console port parameters stored in Setup, the Ampro ROM BIOS deletes the
selected console port from the internal COM port table, normally used by DOS to locate the serial
ports. With the port deleted from the COM port table, DOS cannot change its parameters. Because
it is not listed in the BIOS COM port table, it is not assigned a COMn designation (COM1, COM2,
etc.).
Universal Serial Bus (USB) Ports
The Universal Serial Bus connects USB devices with a USB host, in this case, the Little Board P6d
module. The USB physical interconnect is a tiered star topology, or tree, consisting of hubs and
USB devices. Each USB segment is a point-to-point connection between hubs or between hubs and
USB devices. The entire tree can support up to 127 USB devices. The USB interface standard is
for keyboards, mice, modems, digitizer pads, and other low- to medium-speed peripherals. The bus
can run at 12Mbps or 1.5Mbps, depending on the pull-up resistor on the peripheral device. A 1.5k
ohm pull-up on the +data line sets the speed to 12Mbps. A 1.5k ohm pull-up on the -data line sets
the speed to 1.5Mbps. The power to the peripheral device is current limited with self-resetting
fuses. Each USB interface is implemented as a two-wire differential pair for data, a power wire, a
ground wire, and a shield wire. The USB port signals appear on the two USB connectors (J4 and
J5), as shown in Table 2-16 and Table 2-17.

Infrared (IrDA) Interface
The Little Board P6d infrared interface provides for a two-way wireless communications port using
infrared as a transmission medium. The Little Board P6d IrDA interface supports both SIR (Serial
Infrared) and FIR (Fast Infrared) standards . The SIR standard allows serial communication at
baud rates up to
115K Baud. The FIR standard allows data rates up to 4Mbps.

On the Little Board P6d module, the IrDA physical link hardware consists of an IR transmit
encoder and IR receiver decoder. To implement an IrDA port, the OEM must supply an IR
transducer, which consists of the output driver and IR emitter for transmitting, and the receiver IR
detector. Particular IR transducers may require additional external components.
The IrDA port uses the second serial port to drive its internal encoder/decoder. When using the
IrDA interface, you cannot use serial 2 as an RS232, RS485, or RS422 port.
IrDA Connector (Part of Utility J19)
There are two popular implementations of Fast IR. One uses a separate receive line capable of
receiving at the higher data rate (up to 4 Mbytes/second). The other is implemented with a mode
control line. When the IR port is set for high speed, the mode select line (IRMODE) is high. This
switches the external transceiver to high speed mode. The IrDA port pinout is listed in Table 2-18.

Multi-Mode Parallel Port
The Little Board P6d system incorporates a multi-mode parallel port. This port supports four
modes of operation:
!
!
!
!
Standard PC/AT printer port (output only)
PS/2-compatible bidirectional parallel port (SPP)
Enhanced Parallel Port (EPP)
Extended Capabilities Port (ECP)
This section lists the pinout of the parallel port connector and describes how to configure it for its
I/O port and interrupt assignments, how to assign a DMA channel to the port when operating in
ECP mode. And programming information, including how to use the port for bidirectional I/O.
I/O Addresses and Interrupts
The parallel port functions are controlled by eight I/O ports and their associated register and
control functionality. The Little Board P6d parallel port is assigned to the primary parallel port
address normally assigned to LPT1 and cannot be changed. You may disable the port in Setup to
free the hardware resources for other peripherals.
The parallel port can be configured to generate an interrupt request upon a variety of conditions,
depending on the mode the port is in. Assignment of an interrupt to the parallel port is optional,
and its use depends on software requirements and which mode of operation you are using. IRQ 7 is
the default parallel port IRQ assignment. Table 2-19 lists the parallel port addresses and IRQs.

ROM-BIOS Installation of Parallel Ports
Normally, the BIOS assigns the name LPT1 to the primary parallel port, and LPT2 to the secondary
parallel port (if present), and so on. However, the BIOS scans the standard addresses for parallel
ports and if it only finds a secondary port, it assigns LPT1 to that one. Therefore, if the Little
Board’s parallel port is enabled, it will be assigned LPT1 by the BIOS. If it is disabled and there is
another parallel port in your system, that port will be assigned LPT1 by the BIOS.
2-19
The ROM-BIOS scans I/O addresses for parallel ports in the following order: 3BCh, 378h, 278h.
DMA Channels
In ECP enhancement mode, the parallel port can send and receive data under control of an on-
board DMA controller. On the Little Board P6d module, select a DMA channel in Setup. You can
configure the parallel port to use either DMA channel 1 or DMA channel 3. If you will not be using
DMA with the parallel port, leave it disabled. This makes the DMA channel available to other
peripherals installed on the expansion buses.
Parallel Port Connector (J9)
The parallel port appears on J9. Its pinout is arranged so that a 26-pin ribbon cable can be directly
connected to a 25-pin DB-25 connector to match the PC standard pinout.
Table 2-20 gives the connector pinout and signal definitions for the parallel port. In addition, the
table indicates the pins to which each signal must be wired for compatibility with a standard DB25
connector. Normally the PC parallel port uses a female “DB“ connector.

Note
For maximum reliability, keep the cable between the board and the
device it drives to 10 feet or less in length.
IEEE-1284-compliant Cables
Using the parallel port for high-speed data transfer in ECP/EPP modes requires special cabling for
maximum reliability.
Some of the parameters for a compliant IEEE-1284 cable assembly include:
All signals are twisted pair with a signal and ground return
Each signal and ground return should have a characteristic unbalanced impedance of 62 +/- 6 ohms
within a frequency band of 4 to 16MHz
The wire-to-wire crosstalk should be no greater than 10%
Please refer to the IEEE-1284 standard for the complete list of requirements for a compliant cable
assembly, including recommended connectors
2-21
Latch-Up Protection
The parallel port incorporates chip protection circuitry on some inputs, designed to minimize the
possibility of CMOS “latch up” due to a printer or other peripheral being powered up while the
Little Board P6d system is turned off.
Parallel Port Registers
The low-level software interface to the parallel port consists of eight addressable registers. The
address map of these registers is shown in Table 2-21.

Standard and Bidirectional Operation
You can use the parallel port as a standard output-only printer port or as a PS/2-compatible
bidirectional data port with up to 12 output lines and 17 input lines. All data and interface control
signals are TTL-compatible. Set the parallel port’s default mode using Setup.
Using the Parallel Port in Bidirectional Mode
To use the port as a bidirectional data or digital control port you must set the default mode to
bidirectional in Setup or put it in bidirectional mode with a BIOS call. The following code example
shows how to set the parallel port mode to bidirectional.
;----------------------------------------------------------

; AMPRO command
; AMPRO function
; Extended mode (use 00 to set output-only mode)
Within bidirectional mode, the port can be in its input state or output state. The code shown above
leaves the port in its input state. An IN instruction of I/O address 378h reads the current state of
the data lines.
2-22
Little Board P6d Module
To change the port between input and output states, write a 1 to bit five of the control register to
set the port to its input state; or a 0 to set it to its output state. Here is a code sample for
dynamically changing the port direction (after it is in Extended Mode).

Using the Control Lines for Additional I/O
Besides the eight data lines, you can use the four control lines (STB*, AUTOFD*, INIT*, and
SELIN*) as general purpose output lines. Similarly, you can use the five status lines (ERROR*,
SLCT, PE, ACK*, and BUSY) as general purpose input lines.
You can read the four control lines and use them as input lines. These lines have open collector
drivers with 4.7k ohm pull-ups. To use a control line as an input line, you must first write to its
corresponding bit in the control register. If the line is inverting (*), write a 0, otherwise write a 1.
This will cause the line to float (pulled up by the 4.7k ohm resistors). When a line floats, you can
use it as an input.
Enabling the Parallel Port Interrupt
Bit 4 in the Control Register enables the parallel port interrupt. If this bit is high 1, then a rising
edge on the ACK* (IRQ) line will produce an interrupt on the parallel port interrupt, IRQ7. Table
2-22 lists the parallel port register bits. Parallel port register bit definitions are described in Table
2-23.

Floppy Drive Considerations
Nearly any type of soft-sectored, single or double-sided, 40 or 80 track, 5-1/4 inch or 3-1/2 inch
floppy disk drive is usable with this interface. Using higher quality drives improves system
reliability. Here are some considerations about the selection, configuration, and connection of
floppy drives to the Little Board P6d module.
Drive Interface—The drives must be compatible with the board’s floppy disk signal interface, as
described below. Ampro recommends any standard PC-or AT-compatible 5-1/4 inch or 3-1/2 inch
floppy drive.
Drive Quality—Use high quality, DC servo, direct drive motor floppy disk drives.
Drive Select Jumpering—Both drives must be jumpered to the second drive select.
Floppy Cable—For systems with two drives, use a floppy cable with conductors 10-16 twisted
between the two drives. This is standard practice for PC-compatible systems.
Head Load Jumpering—When using drives with a Head Load option, jumper the drive for head load
with motor on rather than head load with drive select. This is the default for PC-compatible drives.
Drive Mounting—If you mount a floppy drive very close to the Little Board or another source of
EMI, you may need to place a thin metal shield between the disk drive and the device to reduce the
possibility of electromagnetic interference.
Floppy Interface Configuration
The floppy interface is configured using Setup to set the number and type of floppy drives connected
to the system. Refer to the Setup section starting on page 2–48 for details.
2-25
If you don’t use the floppy interface, disable it in Setup. This frees the floppy’s I/O addresses, IRQ6,
and DMA channel 2 for use by other peripherals installed on the PC/104 bus.
Floppy Interface Connector (J14)
Table 2-25 shows the pinout and signal definitions of the floppy disk interface connector, J14. This
pinout does not meet the AT standard for floppy drive cables. An adapter board can be purchased
from Ampro that will interface the 26-pin 2mm connector to a standard 3.5” floppy disk connector.

EIDE Hard Disk Interface
The Little Board P6d system provides an interface for up to four Integrated Device Electronics
(IDE) peripheral devices, such as hard disk drives and CD-ROM drives.
The primary IDE interface appears at connector J6, a 44-pin 2mm, dual-row connector.
The secondary IDE interface appears at connector J7, also a 44-pin 2mm, dual-row connector.
Table 2-26 shows the interface signals and pin outs for the IDE interface connectors. Both pinouts
are identical.

IDE Interface Configuration
Use Setup to specify your IDE hard disk drive types. See the Setup section beginning on page 2-48
for details.
If you do not find a drive type whose displayed parameters match the drive you are using, use drive
type USER. It allows you to manually enter the drive’s parameters. The drive manufacturer
provides the drive parameters—check the drive’s documentation for the proper values to enter.
If you are using a newer IDE drive, use drive type AUTO. It automatically configures the drive
type parameters from information provided by the drive itself.
CompactFlash Solid-State Disk
The Little Board P6d system supports a CompactFlash device, a solid-state IDE hard-disk emulator.
It acts as a removable hard-disk drive. You can format, read, and write the CompactFlash device
much as you would any standard IDE drive.
Enabling the Drive
The CompactFlash interface emulates an IDE drive to the operating system. However, the
CompactFlash interface takes up one of the positions of the primary IDE drive controller.
Note
If you use the CompactFlash interface, you can only add one
additional hard drive to the primary IDE controller.
Master/Slave Setting
The CompactFlash interface can be configured to emulate a master or slave IDE device in the
system.
To configure the drive as master, install a jumper on W1.
To configure the drive as slave, remove the jumper on W1.
Note
The IDE drive attached to the primary IDE controller must have the
opposite setting.
Solid-State Disk Preparation
To prepare CompactFlash device for use in the system, insert the device. Boot the system and
prepare the drive just as you would a new IDE drive. That is, use the DOS FDISK utility to set up
one or more partitions, and then use the DOS FORMAT utility to format the drive.
A CompactFlash device, properly formatted and programmed, can be used as a boot drive. To do so,
you must configure the drive to be master by installing a jumper on W1. First FDISK the device as
a primary DOS partition, then format the drive using the /S option to include the DOS operating
system.

Flat Panel/CRT Video Controller
The Little Board P6d system provides an integrated high-performance super-VGA video controller.
The standard video controller supports both CRT and flat panel displays, but only supports 3.3V
video panels.
Note
If you are using 5V panels, an Application Note can be downloaded,
which describes how to build a 3.3V-to-5V converter, or you can order

Connecting a Flat Panel (J15)
Signals for a wide range of flat panel displays, both color and gray-scale, appear on the Flat Panel
connector. Although flat panels of a similar type use similar sets of signals from the video
controller, these do not share a standardized interface connector pin configuration. The names of
panel control signals vary from manufacturer to manufacturer. Read the description of each signal
carefully to determine how each signal is to be used for your chosen display. Refer to the panel
manufacturer’s technical literature to determine how to wire a cable for your chosen panel and
application.
In many applications, the power management functions control the LCD display; for example, in
portable equipment. Furthermore, power and signals must be sequenced at the proper time when
the system is energized to prevent damage to the display. The Little Board P6d video controller
provides power and signal conditioning to meet these requirements. Table 2-31 lists the signals
available on the Flat Panel connector.

Power Sequencing
Some LCD flat panel displays can be damaged if the voltage and data signals are applied at power
up. This can result in damage to the panel or reduction of its operational life. The LB P6d module
provides the control signals for switching the power supply lines to protect the flat panel. Power to
the panel must be enabled using the special enable signals provided on the flat panel connector,
ENAVEE, ENAVDD, and ENABKL.
Advanced Power Management
The same signals that support power sequencing are also used to provide the power management
feature. In “panel off mode” both the CRT and flat panel interfaces are turned off, but the VGA
subsystem (registers and display memory) remain powered. In “standby mode”, the CRT and flat
panel interfaces are turned off, and in addition, the VGA subsystem is turned off. The screen
DRAM is placed in a low-power mode in which only the DRAM is refreshed.

BIOS Support of Standard Flat Panels
The Little Board P6d system can support flat panel BIOS settings for up to 16 popular LCD panels,
but only 8 have been configured in the BIOS. You select which flat panel BIOS settings to use in
Setup. For details about configuring the video controller, refer to the description of the Integrated
Peripherals Setup on page 2–48. For the current list of supported panels types, refer to Table 2-48.
If you plan to use an unsupported panel, you must modify the standard BIOS to support the panel.
Ampro can provide a BIOS modification kit to you for this purpose. The new video BIOS is then
loaded into the on-board Flash device.
To install the new video BIOS code in the on-board OEM Flash memory device:
1. Install jumper W2 to write-enable the Flash device.
2. Install your new video BIOS code in the on-board Flash device using a utility called
PGM6X.COM, supplied by Ampro on the utility disk that comes with the Little Board P6d
Development Platform.
3. Remove W2 to write-protect the on-board Flash device.
PGM6X is a DOS utility designed to write to the on-board Flash device (The on-board Flash device
contains the system’s BIOS and the video BIOS). Instructions for this utility are provided on the
utility diskette. Contact your Ampro sales representative or Ampro Technical Support for
information about the Little Board P6d Flat Panel BIOS Modification Kit.
Connecting a CRT (J17)
Analog video signals from the video controller appear on a 10-pin dual-row header. These signals
are compatible with the standard video monitors commonly used with desktop PCs. Specifications
for compatible monitors are provided in Chapter 3, Technical Specifications.
Normally, the signals are connected to a standard DB-15 video connector by a “transition cable,”
made from a ribbon cable connectors and a short length of 10-wire ribbon cable. A transition cable
can connect the video signals to a bulkhead-mounted DB-15 connector, allowing any standard CRT
to be easily connected using a standard monitor video cable.
+5V power, protected by a fuse, can supply power to an external device, such as an NTSC Video
adapter module. Table 2-32 gives the signal pinout of J17 and pin connections for a DB-15
connector. Table 2-33 shows mating connectors.

Ethernet Network Interface
This section describes the hardware of the Ethernet interface and discusses relevant software
considerations.
Hardware Description
The Ethernet subsystem is based on the Intel 82559ER 10/100BasetT PCI Ethernet Controller. The
Ethernet controller fully supports IEEE 802.3 Ethernet standards, and supports standard 10BaseT
and 100BaseT via a standard RJ45 connector.
The Ethernet controller interfaces to the PCI portion of the bus. Features of this controller include:
!
!
!
Speed auto-negotiation (complies with IEEE802.3 standard)
Full-duplex operation at 10 Mb/s and 100 Mb/s
Low-power energy modes
Ethernet RJ45 Interface Connector (J13)
The Ethernet connector is a standard RJ45 jack for connecting directly to an Ethernet network
using category 5 UTP/STP cabling.

Ethernet Interface Software
Manufacturer's Ethernet ID
Each manufacturer of Ethernet network adapters and interfaces is assigned a unique
manufacturer's ID by the IEEE Standards Office. A network address consists of 48 bits. The upper
24 bits are the manufacturer's ID and the lower 24 bits are the board's unique ID.
For developers who are creating network applications, knowing the manufacturer's ID for network
adapters attached to the network may or may not be important.
Ampro's 24-bit manufacturer's ID for Ethernet controllers is displayed in hex as follows:
00 40 53
Network Operating Systems
The Ethernet interface is typically connected in a network controlled by a network operating
system. The network operating system may be part of the computer's operating system or be
provided separately. For example, Windows® NT provides the network operating system as part of
a computer's operating system. Novell's NetWare™ provides a separate, add-on network operating
system for DOS and Windows. The network operating system provides file server and network
services to the distributed systems connected to the network. Each node on the network must have
a compatible network operating system installed as well.
Modern network architectures are based on the OSI model, which defines layers of software
between the network hardware, the network operating system, and the applications that use the
network services. The actual Ethernet cable and the Little Board P6d hardware interface are at the
bottom level. A driver program at the next level handles communication between the hardware and
the operating system, masking any unique differences in the hardware from the layers above it,
including the network operating systems.
Network OS Drivers
The Little Board P6d Ethernet subsystem uses Intel drivers available from Intel. The driver is the
only unique software you need to use the Little Board P6d system. The supported network
operating systems provide the other software layers normally provided in the OSI model. These
include:
AHSM ODI Drivers (DOS, OS/2, Server)
CHSM ODI Driver for NetWare 5.0
NDIS 2.0.1 Drivers (DOS version 6.x, OS/2 version 3.x and 4.x)
NDIS 3.x MAC Drivers (for WFW 3.11; NT versions 3.5, 3.51, 4.0; Win95)
NDIS 3.x Miniport Drivers (for Windows 95 and Windows NT 3.51)
NDIS 4.x Driver (for Windows NT 4.0 and Windows 95 OSR 2)
Novell UnixWare Drivers (for v1.1 and 2.0)
There are also drivers for various flavors of UNIX and for other operating systems. Intel also
supplies diagnostic software for testing your Ethernet setup.
For the most up-to-date drivers and utility software, please refer to the Intel web page:
2-38
Little Board P6d Module
Note
Intel updates its web site frequently and this location could move in
the future.
Ethernet Setup
This section describes how to configure and connect the Ethernet LAN interface.
There are no jumpers to set on the Ethernet interface, and no hardware configuration, other than
connecting the network cable to an appropriate connector.
Software configuration of the Ethernet interface includes the following steps:
1. In Setup, enable the Ethernet interface.
2. Install the proper driver for the network operating system you will be running. Follow Intel’s
instructions for installing your driver.
Ethernet Indicator LEDs
Two LED indicator lamps are provided on the board to indicate the status of the Ethernet interface.
You can use these LEDs as simple trouble-shooting aids when connecting to an Ethernet segment.
Table 2-37 shows the meaning of each LED.

Watchdog Timer
The watchdog timer function restarts the system if a mishap occurs. Possible problems include:
failure to boot properly; application software losing control; temporary power supply problems;
failure of an interface device; unexpected conditions on the bus; or other hardware or software
malfunctions. The watchdog timer helps assure proper start-up after an interruption. The Little
Board P6d ROM-BIOS supports the board’s watchdog timer function in two ways:
There is an initial watchdog timer setting, specified using SETUP, which determines whether the
watchdog timer monitors the system boot, and if so, how long the time-out is (30, 60, or 90 seconds).
Set the initial time-out (using SETUP) long enough to guarantee that the system can boot and pass
control to the application. Then, the application must periodically retrigger the timer by reading
I/O Port 201h so the time-out does not occur. If the time-out does occur, the system will respond as
determined by how the watchdog timer jumper, W8, is set (see Chapter 2).
There is a standard ROM-BIOS function which may be used by application software to start and
stop the watchdog timer function. Ampro provides the WATCHDOG program that you can use from
the command line or in a batch program to manage the watchdog timer. It is described in the
2-39
Ampro Common Utilities manual. The following simple assembly language routine illustrates how
to control the watchdog timer using the Ampro ROM-BIOS function provided for this purpose:

Utility Connectors (J19)
The Utility connector is 44-pin dual row 2mm. Several functions appear on the Utility connector.
Table 2-38 shows the pinout and signal definitions. Since there are connections for diverse features
on this single connector, a discrete-wire connector is recommended. Table 2-39 shows
manufacturer’s part numbers for both types of mating connectors.

PC/104-Plus Expansion Bus
The PC/104-Plus expansion bus appears on three header connectors, J1, J2, and J3. J1 is a 64-pin
female dual-row header. J2 is a 40-pin female dual-row header, and J3 is a 120-pin 2mm female
quad-row header (4 x 30). The PC bus subset of the PC/104-Plus expansion bus connects to J1. The
AT expansion bus signals connect to J2. The layout of signals on J1 and J2 is compliant with the
PC/104 bus specification, and make up the ISA bus portion of the PC/104-Plus bus. An
implementation of the PCI bus appears on J3.
PC/104-compatible expansion modules can be installed on the Little Board P6d expansion bus. The
buffered output signals to the expansion bus are standard TTL level signals. All inputs to the Little
Board P6d system operate at TTL levels and present a typical CMOS load to the expansion bus.
On-board MiniModule Expansion Details
When installed on the PC/104 expansion bus headers, expansion modules fit within the Little Board
P6d module's outline dimensions. You can install one or more Ampro MiniModule products or other
PC/104 modules on the Little Board P6d expansion connectors. When installed on J1 and J2, the
expansion modules fit within the Little Board P6d module’s outline dimensions.
2-43
Most Ampro MiniModule products have stackthrough connectors compatible with the PC/104
specification. You can stack several modules on the Little Board P6d headers. Each additional
module increases the thickness of the package by 0.66 inches (15 mm). Thus, a 3-module system
fits within the outline of the Little Board and within a 2.4-inch vertical space.
Figure 2-6 shows an example of how PC/104 modules stack on the Little Board P6d module.

Using Standard PC and AT Bus Cards
Ampro offers several options that allow you to add conventional 8-bit and 16-bit ISA expansion
cards to the Little Board P6d system. Contact Ampro for further information about optional bus
expansion products.
Expansion Bus Connector Pinouts
Table 2-43 and Table 2-44 show the pinout and signal functions on the ISA portion. Table 2-45
shows the PCI portion of the PC/104-Plus expansion bus connectors. These include J1, J2, and J3.
The expansion bus pin numbers for J1 and J2 correspond to the scheme normally used on ISA
expansion bus card sockets. Rather than numerical designations (1, 2, 3) they have alpha-numeric
designations (A1, A2…, B1, B2…, etc.). Similarly, the rows of J3 are designated A, B, C, and D.
The Little Board P6d system does not generate ±12VDC, 3.3V, or -5VDC for the expansion bus. If
devices on the bus require these voltages, -12V and -5V can be supplied to the bus connector from
the Utility 1 connector (J19). +12V can be supplied through J10-4. If a PCI peripheral board
requires 3.3V, you can attach this voltage to J10-5.

Setup
Many options provided on the Little Board P6d system are controlled by the Setup function. The
parameters are displayed on several screens, selected from a main menu screen. To configure the
board, you modify the fields in these screens and save the results in the on-board configuration
memory.
The configuration memory consists of portions of the CMOS RAM in the battery-backed real-time
clock chip and an Ampro-unique configuration EEPROM. To enhance embedded-system reliability,
the contents of the EEPROM mirror the contents of the CMOS memory. The EEPROM retains your
configuration information even if the clock’s backup battery fails.
The Setup information is retrieved from configuration memory when the board is powered up or
when it is rebooted with a CTL-ALT-DEL key combination. Changes made to the Setup parameters
(with the exception of the real-time clock time and date settings) do not take effect until the system
is rebooted.
The Setup program is located in the ROM BIOS. To access Setup, press DEL while the computer is
in the Power On Self Test (POST), just prior to booting. This is called hot key access. The screen
will display a message indicating when entering DEL will access Setup.
Some Setup fields, for example, the amount of DRAM memory installed on the board, are read-only
fields, intended for informational purposes only.
Setup Help
You can access help information for many of the Setup options by pressing F1. The information is
displayed in a popup window. Some help screens list all the available option settings, while others
display additional information. Table 2-46 summarizes the choices found on each Setup page.

Figure 2-8. Setup 2 — Standard CMOS Setup
The Standard CMOS Setup screen allows you to configure the following parameters:
!
DATE – Requires the numeric entry of mm:dd:yyyy. Calendar month is displayed and year
requires all 4 digits of century plus year.
!
!
No parameters are displayed for auto-detect hard disk.
The value displayed for Other Memory is required and utilized for system BIOS, video BIOS,
and other system extension ROM shadowing. It is not available for general OEM use.
!
!
HARD DISK – When Auto TYPE is used the MODE should also be AUTO.
When using any IDE hard drive, Auto is the best choice.
EIDE Hard Disk Drives
The module supports up to two hard disk drives connected to the IDE interface. Only hard disk
drives are directly supported in the system’s ROM BIOS. IDE CD-ROM drives and other IDE-
interfaced peripherals are configured by software or drivers supplied separately.
Physical drives can have one or more logical partitions. You can install up to eight logical drives
using drive partitions. To configure the system for the IDE hard drives in your system, set the
drive parameters with Setup, as outlined here:
Drive Types — the configuration memory contains a default list of parameters that specify the
physical format of each drive. Each type specifies the total number of cylinders, number of heads,
cylinder to begin precompensation, landing zone cylinder number, and the number of sectors per
2-51
cylinder. The drive manufacturer supplies these parameters. The list contains “legacy values”,
standard for PCs — a number of older (smaller) drives are defined.
Drive type USER lets you enter drive parameters manually. If no built-in drive type matches your
drive, select drive type USER and enter the drive parameters in the fields provided.
Drive type AUTO selects Autoconfigure. Autoconfigure queries the drive for its parameters. Most
modern drives will respond to the query, allowing the BIOS to set the drive parameter values
automatically. This option also provides Logical Block Addressing (LBA) capability, which is used
to support drives larger than 512MB.
Note
LBA uses a translation scheme to convert physical heads, sectors and
cylinders to logical block numbers. Due to differences in the
translation schemes used by different system BIOSs, LBA-compatible
drives that have been formatted on Ampro systems may not function
properly in other systems that support LBA mode. However, due to
the intelligent translation algorithm in the Ampro BIOS, drives
formatted in other systems are likely to be usable on the Little Board
P6d CPU. This only applies to IDE drives that support LBA mode.
Consult the technical literature for the drive you select to find out if it
supports LBA mode.
Drive Selection
Besides specifying the physical characteristics of each IDE drive, you must also specify whether a
drive is a master or slave drive. The first drive in a system is always configured as a master drive.
A second drive would be a slave drive. Each manufacturer may use a different scheme to handle
the master and slave relationship, so drives from different manufacturers may not be compatible.
Be sure to test drive compatibility in systems with two IDE drives.
Drives default to master from the factory, so if you only have one IDE drive in a system it is
generally already set up properly.
Once you have set the system’s configuration memory, the IDE drive(s) can be formatted and
otherwise prepared normally. Refer to your operating system and disk drive documentation for
specific procedures and requirements.
Floppy Drives
The ROM BIOS supports all of the popular DOS-compatible floppy disk formats. This includes all
the 5-1/4 inch and 3-1/2 inch floppy formats — 360K, 720K, 1.2M, and 1.44M.
Drive Parameter Setup
Enter the number and type of floppy drives in the system. If the drives connected to the system do
not match the parameters in the configuration memory, POST displays an error message. To
eliminate the error message, set the drive parameters to match your floppy drives.
2-52
Little Board P6d Module
Video
Specify the initial video mode. Select Mono, CGA40, CGA80, or EGA/VGA. If your video display
card is VGA, super VGA, or any other high resolution standard, specify EGA/VGA no matter how it
is configured to come up.
Error Halt
Select which kinds of errors will halt the Power-On Self Test (POST). If you plan to use the module
without a keyboard, be sure to set this option to not halt on keyboard error.
DRAM Memory
The ROM BIOS automatically detects the amount of memory during POST and stores the result
when you save the configuration values when exiting Setup. This Setup page displays the amount
of memory found in the system.

!
Power Management Timers — These timing modes are only configurable if the Power
Management option is set to User Defined. Each timer sets the amount of idle time before the
system enters the specified power-saving mode. These modes are:
–
Doze Mode — This mode reduces the CPU clock speed after a set time of system inactivity, when
it is enabled. Other devices remain active.
–
Standby Mode — This mode reduces the CPU clock speed and shuts down the disk drives and
video monitor after a set time of system inactivity, when it is enabled. Other devices remain
active.
–
–
Suspend Mode — This mode shuts down all activities except DRAM refresh after a set time of
system inactivity,.
HDD Power Down — This mode shuts down the hard disk drives after a set time of system
inactivity, when it is enabled. All other devices remain active.
–
–
Throttle Duty Cycle — This mode selects a percentage of time the CPU runs in Doze Mode.
PCI/VGA Active Monitor — This mode restarts the Standby Mode timer, if there is any video
activity, when enabled.
–
–
Soft-Off by PWR-BUTTN — This mode enables the PWR-BUTTN (Power Button) input. A 4
second signal from this input will cause a power-down of all on-board systems. External power is
not controlled. The CPU fan may still run.
Power-On by Ring (also Resume by Ring) — The mode uses a ring to power on the board, but is
Disabled by default. When power is suspended to the board, Windows shuts down and power is
removed from the ring input. This also causes the ring input to act as a startup event if a ring
occurs, which will restart the board.
–
–
IRQ 8 Break Suspend — This mode uses the RTC Interrupt to cause the power management
mode to exit.
CPU Fan Off in Suspend — This feature turns off the CPU Fan in suspend mode, or keeps the
fan running, allowing it to cool off the CPU.
!
Reload Global Timer Events — Any of the Reload Global Timer Events will cause the Standby
Mode timer to be restarted when the event is detected.
