1.4 Microprocessor
The motherboard is designed to operate with 3.3 volt Pentium Processors. An onboard linear
voltage regulator circuit provides the required 3.3 volts from the 5.0 volt tap of the power supply.
An on-board jumper enables use of VRE specified processors. Pentium processors that run
internally at 75, 90, 100, 120, 133, 150, 166, and 200 MHz are supported.
The Pentium processor maintains full backward compatibility with the 8086, 80286, i386 and
Intel486 processors. It supports both read and write burst mode bus cycles, and includes separate
8 KB on-chip code and data caches that employ a write-back policy. The Pentium processor
9
LPX Motherboard Technical Product Specification
includes an advanced numeric coprocessor that increases the speed of floating point operations,
while maintaining backward compatibility with Intel486 DX math coprocessor and complying to
ANSI/IEEE standard 754-1985.
1.4.1
Microprocessor Upgrade
The board contains a 321-pin Socket 7 ZIF processor socket. Socket 7 supports a processor
upgrade path that includes higher performance Pentium OverDrive processors than can be
supported with socket 5.
1.5 Memory
1.5.1
System Memory
The motherboard provides four 72-pin SIMM sockets that make it possible to install up to 128 MB
of RAM. The sockets support 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32
(32 MB) single- or double-sided modules. Minimum memory size is 8 MB and maximum
memory size, using four 8M x 32 SIMM modules, is 128 MB. Memory timing requires 70 ns fast
page devices or, for optimum performance, 60 ns EDO DRAM. If the maximum external CPU
clock speed is 60 MHz or slower, 70 ns EDO DRAM may be used. Both parity and non-parity
memory are supported as well as ECC.
The four sockets are arranged in two banks of two sockets each. The sockets are designated Bank
0 and Bank 1. Each bank provides a 64/72-bit wide data path. Both SIMMs in a bank must be of
the same memory size and type, although the different types of memory may differ between banks.
It is even possible to have 70 ns Fast Page DRAM in one bank and 60 ns EDO DRAM in the other,
in which case each bank is independently optimized for maximum performance. Bank 0 only,
Bank 1 only, or both of the banks may be populated. There are no jumper settings required for the
memory size or type, that is automatically detected by the system BIOS. Use only tin lead SIMMs
when adding DRAM.
1.5.1.1
EDO DRAM
Extended Data Out (or Hyper Page) DRAM is designed to improve the DRAM read performance.
EDO DRAM holds the memory data valid until the next CAS# falling edge, unlike standard fast
page mode DRAM which tri-states the memory data when CAS# negates to precharge for the next
cycle. With EDO, the CAS# precharge overlaps the data valid time, allowing CAS# to negate
earlier while still satisfying the memory data valid window time.
1.5.2
Second Level Cache
The Xcelerated Controller device supports a second level cache that uses the high performance
synchronous pipeline burst static RAM (PBSRAM). PBSRAM provides performance similar to
expensive synchronous Burst SRAMs for only a slight cost premium over slower performing
asynchronous SRAMs.
The RU430HX motherboard supports options for 256 or 512 KB cache soldered down. Either
configuration can provide cache for the first 64 MB of system memory. For ease of use the cache
size is automatically detected and configured by the system BIOS for optimal performance.
10
Board Description
1.6 Chipset
The Intel 82430HX PCIset consists of the 82439HX Xcelerated Controller (TXC) and one
82371SB PCI ISA/IDE Xcelerator (PIIX3) bridge chip.
1.6.1
82439HX Xcelerated Controller (TXC)
The 82439HX provides all control signals necessary to drive a second level cache and the DRAM
array, including multiplexed address signals. The TXC also controls system access to memory and
generates snoop controls to maintain cache coherency. The TXC comes in a 324-pin BGA package
and includes the following features:
•
•
•
•
1.6.2

LPX Motherboard Technical Product Specification
1.6.3
IDE Support
The motherboard provides two independent high performance bus-mastering PCI IDE interfaces
capable of supporting PIO Mode 3 and Mode 4 devices. The system BIOS supports Logical Block
Addressing (LBA) and Extended Cylinder Sector Head (ECHS) translation modes as well as
ATAPI (e.g. CD-ROM) devices on both IDE interfaces. Detection of IDE device transfer rate and
translation mode capability is automatically determined by the system BIOS.
Normally, programmed I/O operations require a substantial amount of CPU bandwidth. In true
multi-tasking operating systems like Windows 95, the CPU bandwidth freed up by using bus
mastering IDE can be used to complete other tasks while disk transfers are occurring. When used
in conjunction with the appropriate driver for the Windows 95 environment, the IDE interface can
operate as a PCI bus master capable of supporting PIO Mode 4 devices with transfer rates of up to
16 MB/sec.
1.7 I/O Controller
Control for the integrated serial ports, parallel port, floppy drive, RTC and keyboard controller is
incorporated into a single component, the National Semiconductor PC87306B. This component
provides:
•
•
•
•
•
•
Two NS16C550-compatible UARTs with send/receive 16 byte FIFO
Support for an IrDA compliant Infra Red interface
Multi-mode bi-directional parallel port
 Standard mode; IBM and Centronics compatible
 Enhanced Parallel Port (EPP) with BIOS/Driver support
 High Speed mode; Extended Capabilities Port (ECP) compatible
Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)
Integrated real-time clock accurate within +/- 13 minutes/year at 25° C and +5 V when the
system is continuously powered on
Integrated 8042 compatible keyboard controller
By default, the 87306B interfaces are automatically configured by the BIOS during boot-up. You
can also manually configure the interfaces with the BIOS Setup utility. Chapter 3 describes the
BIOS Setup utility.
1.7.1
Floppy Controller
The I/O controller is software compatible with the DP8473 and 82077 floppy disk controllers. You
can configure the floppy interface for 360 KB or 1.2 MB 5¼ inch media or for 720 KB, 1.2 MB,
1.44 MB, or 2.88 MB 3½ inch media with the BIOS setup utility. By default, the Floppy A
interface is configured for 1.44 MB and Floppy B is disabled. A Setup option makes it possible to
prevent a user from being able to write to a floppy drive. A driver is required for configuring the
floppy interface for 1.2 MB 3.5-inch (3-mode floppy) operation.
12
Board Description
1.7.2
Keyboard and Mouse Interface
PS/2† keyboard and mouse connectors are located on the back panel side of the baseboard. The 5V
lines to these connectors are protected with a PolySwitch† circuit that acts much like a self-healing
fuse, re-establishing the connection after an over-current condition is removed. While this device
eliminates the possibility of having to replace a fuse, you should still be sure to turn off the system
power before installing or removing a keyboard or mouse.
The integrated 8042 microcontroller contains the AMI Megakey keyboard and mouse controller
code that, besides providing traditional keyboard and mouse control functions, supports PowerOn/Reset (POR) password protection. The POR password can be defined by the user via the Setup
program. The keyboard controller also provides for the following "hot key" sequences:
•
•
•
1.7.3
<CTRL><ALT><DEL>: System software reset. This sequence performs a software reset of
the system by jumping to the beginning of the BIOS code and running the POST operation.
<CTRL><ALT><+> and <CTRL><ALT><->: Turbo mode selection. <CTRL><ALT><->
sets the system for de-turbo mode, emulating an 25 MHz AT, and <CTRL><ALT><+> sets
the system for turbo mode. Changing the Turbo mode may be prohibited by an operating
system, or when the CPU is in Protected mode or virtual x86 mode under DOS.
<CTRL><ALT><defined in setup>: A power down hot-key sequence takes advantage of the
SMM features of the Pentium Processor to greatly reduce the system’s power consumption
while maintaining the responsiveness necessary to service external interrupts. A security
hot-key sequence provides password protection to the system.
Real-time clock, CMOS RAM and battery
The integrated real-time clock (RTC) is DS1287 and MC146818 compatible and provides a time of
day clock, 100-year calendar with alarm features. The RTC can be set via the BIOS SETUP
program. The RTC also supports 242-byte battery-backed CMOS RAM in two banks which is
reserved for BIOS use. The CMOS RAM can be set to specific values or cleared to the system
default values using the BIOS SETUP program. Also, the CMOS RAM values can be cleared to
the system defaults by using a configuration jumper on the board.
An external coin-cell style battery provides power to the RTC and CMOS memory. The battery
has an estimated lifetime of three years if the system is not plugged into the wall socket. When the
system is plugged in, power is supplied from the power supply’s +5 V standby current to extend
the life of the battery.
1.7.4
IrDA (infra-red) support
A 5-pin interface on the front panel I/O connector is provided to allow connection to a Hewlett
Packard HSDSL-1000 compatible Infra-red (IrDA) transmitter/receiver. For Consumer Ir, a Sharp
GP1U58X (second sourced by Litton), Panasonic PNA4602M, ICX IRR538 and ICX model
IRR638 or equivalent receiver module is required. Both modules can be connected/supported,
however only one can be active at a time. Once the module is connected to the front panel I/O
header, Serial port 2 can be re-directed to either the IrDA or Consumer Ir module. Once
configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA’s
and printers using application software such as LapLink. The IrDA specification provides for data
13
LPX Motherboard Technical Product Specification
transfers at 115 Kbps from a distance of 1 meter. The Consumer Ir is (system) receive only and
can be used to control telephony functions and multimedia operation such as volume control, CD
track change etc.
1.7.5
Parallel port
A 25-pin D-Sub header is provided on the back panel for a multi-mode bi-directional parallel port.
The Parallel port can be configured in the BIOS setup as output only compatible mode,
bidirectional mode, ECP or EPP modes. The highly flexible parallel port can also be assigned to
I/O addresses 278H, 378H, or 3BCH and IRQ’s 5 or 7. Furthermore, a routable DMA scheme
allows Plug ‘N’ Play operating systems such as Windows 95 to route either DMA channels 1 or 3
to the parallel port for ECP mode. EPP BIOS support must be provided by a device driver or TSR.
1.8 Graphics Subsystem
The RU430HX motherboard is available with a factory option of an S3 Trio 64, S3 V+, or
S3 ViRGE SVGA graphics. The RU430HX motherboard supports S3 media channel for
HW MPEG.
1.8.1
S3 Trio 64 Graphics
The RU430HX motherboard is available with the factory option of an S3 Trio64 SVGA graphics
controller with 1 MB of graphics DRAM. The graphics DRAM can be upgraded to 2 MB by

The Trio64 incorporates a 64-bit graphics engine with a 24-bit RAMDAC, dual programmable
clock generators, and a high performance accelerator core in a single device. The on-chip
RAMDAC/clock synthesizer is capable of output pixel data rates of 135 MHz, providing noninterlaced screen resolutions of up to 1280 x 1024 x 256 colors at 75 Hz (with 2 MB of DRAM).
Hardware acceleration for graphics functions such as BitBLTs with ROPs, 2-point line draws,
trapezoidal and polygon fills, clipping and cursor support provide high performance operation
under Windows and other GUI environments. In addition, a fast linear addressing scheme based
upon DCI reduces software overhead by mapping the display memory into the CPU upper memory
address space and permitting direct CPU access to the display memory.
1.8.2
S3 V+ Graphics
The RU430HX motherboard is available with a factory option of an S3 Trio64 V+ SVGA graphics
controller with 1 MB of graphics DRAM upgradeable to 2 MB. The graphics DRAM can be

S3 ViRGE Graphics
The RU430HX motherboard is available with a factory option of an S3 VIRGE SVGA graphics
controller with 2 MB of 50 ns EDO SOJ DRAM. The S3 VIRGE has a high performance 64-bit
2D/3D graphics engine and incorporates the S3 Streams Processor that enables the device to
convert YUV formatted video data to RGB and provides acceleration for scaling the video display
without compromising picture quality or frame rate. The on-chip RAMDAC/clock synthesizer is
capable of output pixel data rates of 135 MHz providing non-interlaced screen resolutions of up to
1280x1024x256 colors at 75 Hz. The 64-bit S3d Engine incorporates the key Windows and other
GUI accelerator functions of BitBLT, line draw and polygon fill. 3D features include flat shading,
Gouraud shading and texture mapping support. Advanced texture mapping features include
perspective correction, bi-linear and tri-linear filtering, MIP-mapping, and Z-buffering. These
features provide the most realistic user experience for interactive 3D applications. In addition, a
fast linear addressing scheme based upon DCI reduces software overhead by mapping the display
memory into the CPU’s upper memory address space and permitting direct CPU access to the
display memory.

Power Supply Connectors
When used with a power supply that supports remote power on/off, the RU430HX baseboard can
turn off the system power via software control (soft-off). The Powerman utility supplied for
Windows 3.1x allows for soft-off as does the shutdown icon in Windows 95 Start menu. The
system BIOS will turn the system power off when it receives the proper APM command from the
OS. For example, Windows 95 will issue this APM command when the user selects “Shutdown
the computer” option. Note that APM must be enabled in the system BIOS and OS in order for the
soft-off feature to work correctly. Power supplies that support soft-off interface to the baseboard
via the 3-pin “PWS CNTRL” connector (J8B1) which is a Molex 2695 connector featuring a
security latch for reliability. In order for the system to recognize the presence of a soft-off power
supply, the supply must tie pin 3 of the PWS Control connector to ground.
The system’s front panel ON/OFF button is connected to the baseboard via the 1x4-pin “PS
SLEEP” header (J2A1). Pins 15 and 16 of this connector should be tied to a SPST momentary
button to support a power button and, likewise, pins 17 and 18 provide support for a energy saving
sleep/resume button. These functions can be integrated into a system as two separate buttons or a
single button. By implementing a DPST momentary button connected to all four pins of the PS
SLEEP connector, both sleep/resume and power on/off functions can be supported via a single
button. In this configuration, pressing the button momentarily (closing the switch) while the
system is off will turn the system on as you would expect (POST is run). Pressing the button while
the system is running (system will beep), causes the system to enter the energy saving Stand By
(sleep) mode. Pressing the button (or keyboard/mouse) while the system is sleeping, causes the
26
Board Description
system to resume to full power and return to whatever application was active before entering sleep
mode. To turn the system off using the front panel button, the button must be pressed (system will
beep) and held down (2 seconds) until the system produces a two-toned beep. At that time the
system will power off. Remember, the system may also be powered off by utilizing the soft-off
feature mentioned above. When the button is pressed again, the system will power on and run
POST. Traditional power supplies with mechanical ON/OFF buttons (those that do not support
soft-off) will bypass these connectors.

The external speaker provides error beep code information during the Power-On Self Test, if the
system cannot use the video interface. If there are no speakers plugged into the audio output jack,
the audio output is redirected to the external speaker.

Infra-Red (IrDA) connector
Serial port 2 can be configured to support an IrDA or Consumer Ir module via a front panel header
connector. Once configured for IrDA, the user can transfer files to or from portable devices such as
laptops, PDA’s, and printers using application software such as LapLink. The IrDA specification
provides for data transfers at 115 Kbps from a distance of 1 meter. Consumer Ir is typically used
for remote control of telephony and multimedia functions.
1.10.15.3
Sleep / resume
When Advanced Power Management (APM) is activated in the system BIOS and the Operating
System’s APM driver is loaded, Sleep mode (Stand-By) can be entered in one of three ways: an
optional front panel “Sleep/Resume” button, a user defined keyboard hot key, or prolonged system
inactivity. The Sleep/Resume button is supported by a 2-pin header located on the front panel I/O
connector. Closing the “Sleep” switch will generate an SMI (System Management Interrupt) to the
processor which immediately goes into System Management Mode (SMM), the so called “Sleep”
mode.
The front panel “Sleep mode” switch must be a momentary two pin SPST type that is normally
open. The function of the Sleep/Resume button can also be achieved via a keyboard hot-key
sequence, or by a time-out of the system inactivity timer. Both the keyboard hot-key and the
inactivity timer are programmable in the BIOS setup (timer is set to 10 minutes by default). To reactivate the system, or “Resume”, the user must simply press the sleep/resume button again, or use
the keyboard or mouse. Mouse activity will only “wake up” the system if a mouse driver is
loaded. While the system is in Stand-By or “sleep” mode it is fully capable of responding to and
servicing external interrupts (such as incoming FAX) even though the monitor will only turn on if
a user interrupt (keyboard/mouse) occurs as mentioned above.
1.10.15.4
HDD LED
This header can be connected to an LED to provide a visual indicator for when an IDE hard drive
connected to the onboard IDE controller is being read or written.
1.10.15.5
Reset
This header can be connected to a momentary SPST type switch that is normally open. When the
switch is closed, the system will hard reset and run POST.

Audio I/O Connector
An optional audio I/O module is available for the RU430HX motherboard. The module contains
all of the necessary audio jacks (Speaker Out, Line IN, Mic IN) and a game port. The module
plugs into a 34-pin header connector on the motherboard. The audio connectors are 1/8-inch stereo
jacks. An additional connector located on the audio I/O module allows routing of the audio jacks
to the front of the chassis. The audio output is connected to the standard PC speaker to provide an
output path that does not require external speakers. If external speakers are plugged into the
attached I/O module, the audio output is redirected to the external speakers. If headphones are
plugged into a front panel speaker jack, the audio is redirected to the headphones.

CD-ROM Audio Input
A four pin connector is provided for interfacing the audio output stream from a CD-ROM reader
into the audio sub-system mixer. This connector is compatible with the typical cable that is
supplied with CD-ROM readers for interfacing to audio add-in cards.
1.10.16.3
Wave Table Upgrade
With the standard audio feature (YMF701) installed, an eight pin header is provided to connect to a
wave table upgrade card for richer sound quality in both DOS and Windows environments. The
wave table upgrade module typically is installed into a standard ISA slot with a cable routed to the
connector.
Compatible wave table upgrade cards are available from several venders; the ICS WaveFront
upgrade module and the CrystaLake Series 2000 wave table product family add a complete General
MIDI compatible music solution to the RU430HX based system.
The advanced audio feature (YMF704) includes wave table sound and the upgrade connector is not
installed.

Password clear (J1F1-A, Pins 1, 2, and 3)
Allows system password to be cleared by moving the jumper from pins 1-2 to pins 2-3 and turning
the system on. The system should then be turned off and the jumper should be returned to the 1-2
position to restore normal operation. This procedure should only be done if the user password has
been forgotten. The password function is effectively disabled if this jumper is in the 2-3 position.
Default is for the password to be enabled (1-2 position).
1.11.3
Clear CMOS (J1F1-A, Pins 4, 5, and 6)
Allows CMOS settings to be reset to default values by moving the jumper from pins 4-5 to pins
5-6 and turning the system on. When the system reports that “NVRAM cleared by jumper”, the
system can be turned off, and the jumper should be returned to the 4-5 position to restore normal
operation. This procedure should be done whenever the system BIOS is updated. Default is for
this jumper to be on pins 4-5.
1.11.4
CMOS Setup Access (J1F1-B, Pins 1, 2, and 3)
Allows access to CMOS Setup utility to be disabled by moving this jumper from the 1-2 position
to the 2-3 position. Default is for access to setup to be enabled (1-2 position).

2.3 Soft-Off Control
The board design supports Soft-off control via the SMM code in the BIOS. This feature is a
manufacturing option. The CS1 pinout of the I/O controller is connected to the Soft-off control
line in the power supply circuit. The registers in the I/O controller that set the I/O address and
control of the CS1 pin are NOT setup until the SMM code is activated. The code performs the
following operations:
OUT 0Ch to I/O port 2Eh
OUT 75h to I/O port 2Fh
OUT 11h to I/O port 2Eh
OUT 00h to I/O port 2Fh
OUT 0Dh to I/O port 2Eh
OUT A0h to I/O port 2Fh
After setting the above registers, any read operation to I/O location 75h will trigger the Soft-off
circuit and turn the power supply off.

3 Motherboard BIOS and Setup Utility
3.1 Introduction
The board uses an Intel BIOS, which is stored in Flash EEPROM and upgraded using a floppy
disk-based program. In addition to the Intel BIOS, the Flash EEPROM also contains the Setup
utility, Power-On Self Tests (POST), APM 1.1, the PCI auto-configuration utility, and
Windows 95 ready Plug and Play. This board also supports system BIOS shadowing, allowing the
BIOS to execute from 64-bit on-board write-protected DRAM.
The BIOS displays a sign-on message during POST identifying the type of BIOS and a five-digit
revision code. The initial production BIOS in the board will be identified as 1.00.01.CY0.
Information on BIOS functions can be found in the IBM PS/2 and Personal Computer BIOS
Technical Reference published by IBM, and the ISA and EISA Hi-Flex AMIBIOS Technical
Reference published by AMI. Both manuals are available at most technical bookstores
3.2 BIOS Flash Memory Organization
The Intel PA28FB100BX 1 Mb Flash component is organized as 128K x 8 (128 KB). Flash
memory is visible at system addresses FFFE0000 - FFFFFFFFh. The Flash device is divided into
four areas, as described in Table 12.

3.3 BIOS Upgrades
Flash memory makes distributing BIOS upgrades easy. A new version of the BIOS can be
installed from a diskette. BIOS upgrades are available to be down loaded from the secure section
on the Intel bulletin board, or Intel’s FTP site.
The disk-based Flash upgrade utility, FMUP.EXE, has three options for BIOS upgrades:
•
•
•
The Flash BIOS can be updated from a file on a disk;
The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the
event that an upgrade cannot be successfully completed; or
The BIOS in the Flash device can be compared with a file to ensure the system has the correct
version.
41
LPX Motherboard Technical Product Specification
The upgrade utility ensures the upgrade BIOS extension matches the target system to prevent
accidentally installing a BIOS for a different type of system.
3.4 PCI IDE Support
The two local bus IDE connectors with independent I/O channel support are setup up automatically
by the BIOS if the user selects “Autoconfiguration” in setup. The IDE interface supports PIO
Mode 3, and Mode 4 hard drives and recognition of ATAPI CD-ROMs, tape drives, and any other
ATAPI devices. The BIOS will determine the capabilities of each drive and configure them to
optimize capacity and performance. For the high capacity hard drives typically available today, the
drive will be automatically be configured for Logical Block Addressing (LBA) for maximum
capacity and to PIO Mode 3 or 4 depending on the capability of the drive. Mixing IDE drives, on
the same cable, that offer different transfer modes is supported. Each drive’s mode is supported
independently. The user is able to override the auto-configuration options by using the manual
mode setting.
3.5 PCI Auto-configuration
The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow
the insertion and removal of PCI cards to the system without user intervention (Plug and Play).
When the system is turned on after adding a PCI add-in card, the BIOS automatically configures
interrupts, I/O space, and other parameters. PCI interrupts are distributed to available ISA
interrupts that have been not been assigned to an ISA card, or system resources. Those interrupts
left set to “available” in the CMOS setup will be considered free for PCI add-in card use. It is
nondeterministic as to which PCI interrupt will be assigned to which ISA IRQ.
The PCI Auto-Configuration function complies with version 2.10 of the PCI BIOS specification.
System configuration information is stored in ESCD format. The ESCD data may be cleared by
setting the CMOS clear jumper to the ON position.
PCI specification 2.1 for add-in card auto-configuration is also a part of the Plug and Play BIOS.
Peer-to-peer hierarchical PCI Bridge 1.0 is supported, and by using an OEM supplied option ROM
or TSR, a PCI-to-PCMCIA bridge capability is possible as well.
3.6 ISA Plug and Play
The BIOS incorporates ISA Plug and Play capabilities as delivered by Plug and Play Release 1.0A
(Plug and Play BIOS V.. 1.0A, ESCD V.. 1.03). When used in conjunction with the ISA
Configuration Utility (ICU) for DOS or Windows 3.x, the system allows auto-configuration of
Plug and Play ISA cards, PCI cards, and resource management for legacy ISA cards. Because the
BIOS supports configuring devices across PCI bridges, release 1.41 or greater of the ICU must be
used with the board to properly view and change system settings. System configuration
information is stored in ESCD format. The ESCD data may be cleared by setting the CMOS clear
jumper to the ON position.
42
Motherboard BIOS and Setup Utility
The BIOS also has a setup option to support the Windows 95 run time plug and play utilities.
When this option is selected, only devices critical to booting are assigned resources by the BIOS.
Device Node information is available for all devices to ensure compatibility with Windows 95.
Copies of the IAL Plug and Play specification may be obtained via the Intel BBS, or via
CompuServe by typing Go PlugPlay.
3.7 Advanced Power Management
The BIOS has support for Advanced Power Management (APM version 1.1). The energy saving
Stand By mode can be initiated by a keyboard hot key sequence set by the user, a time-out period
set by the user, or by a suspend/resume button tied to the front panel sleep connector.
When in Stand-by mode, the board reduces power consumption by utilizing the Pentium
processor’s System Management Mode (SMM) capabilities and also spinning down hard drives
and turning off VESA DPMS compliant monitors. The user may select which DPMS mode (Stand
By, Suspend, or Off) send to the monitor in setup. The ability to respond to external interrupts is
fully maintained while in Stand-by mode allowing the system to service requests such as in-coming
FAX’s or network messages while unattended. Any keyboard or mouse activity brings the system
out of the energy saving Stand By mode. When this occurs the monitor and IDE drives are turned
back on immediately.
APM is enabled in BIOS by default, however, the system must be configured with an APM driver
in order for the system power saving features to take effect. Windows 95 will enable APM
automatically upon detecting the presence of the APM BIOS.
3.8 Language Support
The BIOS setup screen and help messages are supported in 32 languages. There are 5 languages
translated at this time for use; American English, German, Italian, French, and Spanish.
Translations of other languages will available at a later date.
With a 1 Mb Flash BIOS, only one language can be resident at a time. The default language is
American English, and will always be present unless another language is programmed into the
BIOS using the Flash Memory Update Program (FMUP) available on the Intel BBS.
3.9 Boot Options
Booting from CD-ROM is supported in adherence to the “El Torito” bootable CD-ROM format
specification developed by Phoenix Technologies and IBM. Under the Boot Options field in setup,
CD-ROM is one of four possible boot devices which are defined in priority order. The default
setting is for floppy to be the primary boot device and hard drive to be the secondary boot device.
If CD-ROM is selected, it must be the first device. The third and fourth devices are set to disabled
in the default configuration.. The user can add also select network as a boot device. The network
option allows booting from a network add-in card with a remote boot ROM installed.

A copy of “El Torito” is available on the Phoenix Web page
(http://www.ptltd.com/techs/specs.html).
3.10 Flash LOGO Area
The baseboard supports a 4 KB programmable FLASH user area located at EC000-ECFFF. An
OEM may use this area to display a custom logo. The BIOS accesses the user area just after
completing POST. A utility is available from Intel to assist with installing a logo into flash for
display during POST. Contact your local Intel Sales office or authorized distributor for further
information.
3.11 Setup Enable Jumper
A baseboard configuration jumper controls access to the BIOS Setup utility. By setting the jumper
to the disable position, the user is prevented from accessing the Setup utility during the Power-On
Self Test or at any other time. The message prompting the user to press <F1> to enter setup is also
disabled.
3.12 BIOS Setup Utility
The ROM-based Setup utility allows the configuration to be modified without opening the system
for most basic changes. The Setup utility is accessible only during the Power-On Self Test (POST)
by pressing the <F1> key after the POST memory test has begun and before boot begins. A
prompt may be enabled that informs users to press the <F1> key to access Setup. A jumper setting
on the baseboard can be set to prevent user access to Setup for security purposes.

3.12.10.5
IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15
Sets the status of the IRQ. The options are Available and Used By ISA Card. The default is
Available. The PCI auto-configuration code looks here to see if these interrupts are available for
use by a PCI add-in board. If an interrupt is available, the PCI auto-configuration code can assign
the interrupt to be used by the system. If your system contains an ISA agent that uses one of these
interrupts, select Used By ISA Card for that interrupt.
✏
NOTE
IRQ 3, 4, 5, and 7 may not be available in this option, depending on the setting chosen for the
COM1, COM2 and parallel ports in the Peripheral Configuration Subscreen.
IRQ 14 and 15 will not show up as user available. If the on-board IDE controller is not used, these
interrupts will be available to ISA cards. These interrupts can not be used for PCI cards
3.12.11
Security Screen
This section describes the two access modes that can be set using the options found on the Security
screen, and then describes the Security screen options themselves.
3.12.11.1
Administrative and User Access Modes
The options on the Security screen menu make it possible to restrict access to the Setup program
by enabling you to set passwords for two different access modes: Administrative mode and User
mode.
In general, Administrative mode has full access to the Setup options, whereas User mode has
restricted access to the options. Thus, by setting separate Administrative and User passwords, a
system administrator can limit who can change critical Setup values. The actual limitations depend
on whether either the Administrative or User passwords or both are set. (See the table below for a
description of how the passwords actually work together.)
To limit access to who can boot the system, set the User password. This is the password that the
system asks for before booting. If only the Administrative password is set, the system boots up
without asking for a password. If both passwords are set, you can enter either password to boot the
system.
The following table shows the effects of setting the Administrative and User passwords. (The table
is for reference only, and is not shown on the Security screen.) In the table, the statement “Can
change a limited number of options” means you can change the system date and time, the power
management hot key, the User password, the security hot key, and unattended start.
