The TE430VX design accepts Pentium processors operating at 75 MHz, 90 MHz, 100 MHz,
120 MHz, 133 MHz, 150 MHz, 166 MHz, and 200MHz. There is an option of having 256 KB of
Pipeline Burst SRAM soldered onto the motherboard, or a Card Edge Low Profile (CELP)
connector for cache expandability. The memory subsystem is designed to support up to 128 MB of
EDO DRAM, or up to 64 MB of a new memory architecture called SDRAM, in standard 168-pin
DIMM sockets. A type 7 Pentium OverDrive
processors.
The TE430VX motherboard utilizes Intel's 82430VX PCISet. The 82430VX PCIset contains an
integrated PCI Bus Mastering IDE controller with two high performance IDE interfaces for up to
four IDE devices (such as hard drives, CD-ROM readers, and so forth). The SMC FDC37C932FR
Ultra I/O controller integrates the standard PC I/O functions: floppy interface, two FIFO serial
ports, one EPP/ECP capable parallel port, a Real Time Clock, keyboard controller, and support for
†
an IrDA
compatible infrared interface. To provide for the increasing number of multimedia
applications, a Creative Labs Vibra16C audio codec is integrated onto the motherboard. The Vibra

length add-in cards: one PCI and ISA slot share the same chassis I/O panel.
socket provides upgrades to future OverDrive
†
Pro compatible audio. Integrated onto the motherboard
The motherboard is designed to fit standard ATX form factor chassis. Figure 2 illustrates the
motherboard’s dimensions. The motherboard meets the standard ATX specification guidelines in
that the outer dimensions are 12" x 9.6". Location of the I/O connectors, riser slot, and mounting
holes also meet the standard ATX specification.
The motherboard is designed to operate with 3.3 volt Pentium Processors running at 75, 90, 100,
120, 133, 150, 166, and 200MHz. 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.
The Pentium processor maintains full backward compatibility with 8086, 80286, i386 and
Intel486 processors. It supports both read and write burst mode bus cycles and also includes
separate 8 KB on-chip code and data caches that employ a write-back policy.
The Pentium processor is an advanced numeric coprocessor that significantly increases the speed of
floating point operations, while maintaining backward compatibility with i486DX math
coprocessor and complying to ANSI/IEEE standard 754-1985.
This motherboard does not support the keep-out zones around the socket 7 that allow use of a
“piano wire” type heatsink clip. Intel recommends using only metal heatsink clips.
1.4.1 Microprocessor Upgrade
The motherboard provides a 321-pin Socket 7 ZIF processor socket. Socket 7 supports upgrades to
higher performance Pentium OverDrive processors.
1.5 Memory
1.5.1 System Memory
The motherboard provides two 168-pin DIMM(Dual Inline Memory Module) sites for DRAM
memory expansion. The sockets support 1 Meg x 64 (8 MB), 2 Meg x 64 (16 MB), and 4 Meg x
64 (32 MB) SDRAM DIMM modules and 1 Meg x 64 (8 MB), 2 Meg x 64 (16 MB), 4 Meg x 64
(32 MB) and 8 Meg x 64 (64 MB) EDO(Extended Data Out) DIMM modules. For systems
configured with EDO or SDRAM DIMM modules, minimum memory size is 8MB for EDO
systems. Maximum memory size is 128MB for EDO systems. Maximum memory size is 64MB
for SDRAM systems.
The two DIMM sockets are arranged as Bank 0 and Bank 1. Each bank consists of one socket and
a 64-bit wide data path. Bank 0 only, Bank 1 only, or both banks may be populated. EDO and
SDRAM may be installed in the same system. The system BIOS automatically detects memory
size and type so no jumper settings are required. Gold leaded DIMMs are required to be used
when adding system memory.
1.5.1.1 EDO DRAM
E D O (or Hyper Page) DRAM improves 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.

Motherboard Description
1.5.1.2 SDRAM
Synchronous Dynamic Random Access Memory, (SDRAM) is designed to improve main memory
performance. SDRAM is synchronous to the memory clock unlike standard Fast Page DRAM, or
EDO DRAM. All the timing is dependent on the number of memory clock cycles. This makes the
timing design simpler and makes a faster memory speed easier to achieve. Discrete SDRAM
components must meet the 66 MHz PC SDRAM Specification version 1.0 to function correctly.
1.5.2 Second Level Cache
The Pentium processor's internal cache can be complemented by a second level cache using highperformance Pipelined Burst SRAM with GWE (Global Write Enabled) or Asynchronous Cache.
One factory option is an integrated 256 KB direct mapped write-back second level cache
implemented with two 32k x 32 Pipeline Burst SRAM devices that take advantage of the Global
Write Enable pin. A 5v 8 KB x 8 external Tag SRAM provides caching support for up to 64 MB
of system memory.
A second factory option is a Type 1 CELP connector, specified by Intel’s COAST Module
Specification version 3.0. The Type 1 CELP connector has a keying “hip” located at one end of
the connector. This connector allows the use of both a GWE PBSRAM COAST module, and a
GWE Asynchronous COAST module. The GWE Asynchronous modules must be built for Intel’s
82430VX designs and are not interchangeable with Asynchronous modules built for 82430FX
designs. The reason for this incompatibility is the additional logic added to the 82430VX modules
to account for the GWE functionality built into the chipset.
1.6 Chipset
The Intel 82430VX PCIset consists of the 82430VX System Controller (TVX), two Data Paths
(TDX) and one 82371SB PCI ISA/IDE Xcelerator (PIIX3) bridge chip.
1.6.1 82430VX System Controller (TVX)
The 82430VX TVX provides all control signals necessary to drive a second level cache and the
DRAM array, including multiplexed address signals. The TVX also controls system access to
memory and generates snoop controls to maintain cache coherency. The TVX comes in a 208-pin
QFP package that features:
• CPU interface control
• Integrated L2 write-back cache

1.6.2 82430VX Data Path (TDX)
Two 82430VX TDX data path components provide a 64-bit microprocessor to memory path. The
TDX components are controlled by the TVX. They each add one load to the PCI bus and perform
all of the required byte and word swapping. The TDX devices come in a 208 pin QFP package.
1.6.3 PCI ISA/IDE Xcelerator (PIIX3)
The PIIX3 provides the interface between the PCI and ISA buses and integrates a dual channel fast
IDE interface capable of supporting up to 4 devices. The PIIX3 integrates seven 32-bit DMA
channels, five 16-bit timer/counters, two eight-channel interrupt controllers, PCI-to-AT interrupt
mapping circuitry, NMI logic, ISA refresh address generation, and PCI/ISA bus arbitration
circuitry together onto the same device. The PIIX3 comes in a 208-pin QFP package that features:
• PCI Bus and ISA Bus interface
• Universal Serial Bus controller
Host/hub controller
• Integrated fast IDE interface
Support for up to 4 devices
PIO Mode 4 transfers up to
16 MB/sec

bus master PCI IDE burst
transfers
Bus master mode
• PCI 2.1 compliance
• Enhanced fast DMA controller
• Interrupt controller and steering
• Counters/timers
• SMI interrupt logic and timer with
fast on/off mode
1.6.4 IDE SUPPORT
The motherboard provides two independent bus-mastering PCI IDE interfaces that support 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. The system BIOS automatically detects IDE device transfer rate
and translation mode.
Normally, programmed I/O operations require a substantial amount of CPU bandwidth. In true
multi-tasking operating systems like Windows
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.
The SMC FDC37C93FR is software compatible with the DP8473 and 82077 floppy disk
controllers. The floppy interface can be configured for 360 KB or 1.2 MB 5¼" media or for
720 KB, 1.2 MB, 1.44 MB, or 2.88 MB 3½" media in the BIOS setup. By default, the Floppy A
interface is configured for 1.44 MB and Floppy B is disabled. Another setup option prevents the
user from being able to write to floppy. Configuring the floppy interface for 1.25 MB 3 ½"
(3-mode floppy) requires the use of special floppy drives and a driver to for the specific operating
system.
1.7.2 Keyboard and mouse interface
PS/2† keyboard/mouse connectors are located on the back panel side of the motherboard. The 5V
lines to these connectors are protected with a PolySwitch
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, care should be taken to turn off the
system power before installing or removing a keyboard or mouse. The system BIOS can detectand
correct keyboards and mice plugged into the wrong PS/2 style connector.
The integrated 8042 microcontroller contains the AMI Megakey keyboard/mouse controller code
which, 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:
• <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 hotkey sequence provides password protection to the system.

1.7.3 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 motherboard.
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 ATX power supply’s 5v standby current to extend
the life of the battery.
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. Once the module is
connected to the front panel I/O header, Serial port 2 can be re-directed to the IrDA module. When
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
transfers at 115kbps from a distance of 1 meter.
1.7.5 Consumer IR Support
The motherboard also has a signal pin to support Consumer IR devices(remote controls). A
software and hardware interface is required to implement consumer IR on with the motherboard.
1.7.6 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 operates in standard mode, Enhanced Parallel Port (EPP) version 1.7 mode, with
BIOS and Driver support, and a high speed Extended Capabilities Port (ECP) compatible mode.
EPP Mode requires a driver provided by the peripheral manufacturer to operate correctly.
1.8 Graphics Subsystem (S3 Trio64V+)
The motherboard is available with an S3 Trio64 V+ SVGA graphics controller with 1 MB of
graphics memory upgradeable to 2 MB. The graphics DRAM can be upgraded to 2 MB by
installing two 256 KB x 16 SOJ memory devices in the provided sockets. The Trio64 V+ has a
64-bit 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 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’s upper memory address space and
permitting direct CPU access to the display memory.
†
. The IrDA specification provides for data
The motherboard supports the 26-pin VESA feature connector for synchronizing graphics output
with an external NTSC or PAL signal and a shared frame buffer interface to maximize multi-media
performance. Boards configured with the Trio64 V+ will have a 34 pin feature connector that
supports the VESA requirements as well as the LPB (Local Peripheral Bus) that provides a glueless
bi-directional interface to a video companion device such as an MPEG/live video decoder. The
motherboard also supports other VESA standards such as the VESA DPMS protocol to put a
DPMS compliant monitor into power savings modes and the VESA Display Data Channel
(DDC2B) that permits transfer of monitor identification and resolution support data for ease of use.
When a monitor is not plugged into the system on power-up, the video will default to color mode,

Graphics drivers and utilities for Windows 3.11 and Windows 95 are provided on the foundation
software CD. These drivers come in a compressed form and are extracted by using an installation
utility. Also included is a Windows 3.1x control panel applet called Galileo which allows the user
to change the screen resolution, number of colors, and large or small fonts while in Windows.

1.9 Audio Subsystem (Creative Labs Vibra 16C)
The motherboard features a 16-bit stereo audio subsystem. The audio subsystem is based upon the
Creative Labs Vibra 16C (CT2505) multimedia Codec. The Vibra 16C provides all the digital
audio and analog mixing functions required for recording and playing of audio on personal
computers. The Creative Labs Vibra 16C is a single chip VLSI solution which integrates FM
synthesis, is Sound Blaster compatible and Roland MPU-401 UART mode compatible. Creative
Labs Vibra 16C also provides MPCII, Adlib, and Multimedia PC Level 2 compliance to meet all of
the requirements of today’s multi-media applications.
The Vibra 16C has been implemented as a Plug and Play motherboard device. This means that
there is a device node defined for the Vibra 16C and the BIOS must configure it. Although it is
not a Plug and Play device, the Vibra 16C is very flexible in that it accommodates a variety of I/O
addresses, DMA channels and interrupts.
The audio subsystem requires up to two DMA channels (to support full duplex operation) and one
interrupt. When the Vibra 16C is programmed for full duplex operation, two DMA channels are
assigned: one of the channels will be a 16-bit channel and the other will be 8 bits. The system can
be configured to use either DMA channels 1 or 3 (8 bit channels) and DMA channels 5 or 7 (16 bit
channels). The interrupt can be mapped to IRQ 5, 7, 9, or 10. The base address register is also
configurable for a variety of base addresses ranging from I/O address 220 through address 280 (see
the resource map below for more details). The ICU (ISA Configuration Utility) must be installed
and configured before installing the DOS and Windows audio drivers.

1.9.2 Audio Drivers
Audio software and utilities are provided via the foundation software CD for the motherboard for
DOS, Windows 3.1x, and Windows 95. A setup program installs the appropriate software
programs and utilities onto the system hard drive. Included in the audio software are DOS utilities
that allow the user to play a CD-ROM, control sound volume and mixer settings, run diagnostics,
and switch between Sound Blaster Pro and Windows Sound System modes. Windows drivers and
utilities include the Windows sound driver, audio input control panel, audio mixer control panel,
and a business audio transport utility.

When used with a power supply that supports remote power on/off, the motherboard can turn off
the system power via software control (“soft-off” is a manufacturing option). 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. APM must be enabled in the system BIOS and OS in
order for the soft-off feature to work correctly. In order for the system to recognize the presence of
a “soft-off” power supply, the supply must tie pin 14 of the PWS Control connector (J7M2) to
ground. If power to the system is interrupted due to a power outage or the power cord being
unplugged, when power is reapplied, the system will return to the state it was in when the power
was disconnected. If the system was turned on when power was disconnected, the system will turn
back on when power is reapplied.
CAUTION
If the coin-cell battery is removed from the motherboard and AC power is disconnected, the next
time the system is plugged in, power will automatically be turned on without pushing the “on”
button. BIOS can detect this condition, and will attempt to turn off the power supply when this
occurs. This is due to functionality of the SMC I/O controller.
The motherboard provides header connectors to support functions typically located on the chassis
bezel. Front panel features supported include:
• System Reset
• Power LED
• Hard Drive activity LED
• System Speaker
• Infra-Red (IrDA) port
• Sleep/Resume

The speaker provides error beep code information during the Power-On Self Test if the system
cannot use the video interface. As a manufacturing option, an on-board piezoelectric speaker may
be present. The on-board speaker may be disabled by removing a jumper from the front panel
speaker connector and connecting an off-board speaker in its place. The speaker is not connected
to the Creative Labs audio subsystem, so it will not receive output from the audio subsystem.

Motherboard Description
1.10.11.2 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.
1.10.11.3 Sleep or Power LED
This header can be connected to an LED to provide a light when the system is powered on. This
LED will also blink when the system is in a power-managed state.
1.10.11.4 HD 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.
1.10.11.5 Infra-Red (IrDA) connector
Serial port 2 can be configured to support an IrDA module via a 5 pin 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. A pin is also designated for hardware Consumer
IR support.
1.10.11.6 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 (pins 3 and 4) located on the
front panel I/O connector (J9E2). 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” 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 re-activate 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 “sleep” mode it is fully capable of responding to and servicing external interrupts
(such as in-coming FAX) even though the monitor will only turn on if a user interrupt
(keyboard/mouse) occurs as mentioned above
For power supplies that support the Remote ON/OFF feature, this 2 pin header (see Figure 4 pins
1 and 2 of J9E2) should be connected to the system power ON/OFF switch. The power ON/OFF
button should be a momentary SPST switch that is normally open. The power supply control
signal (PS_ON) is supported via the primary power connector. Traditional power supplies with
mechanical ON/OFF switches that do not support remote ON/OFF or “soft-off” will by-pass this
circuit.
After turning the system ON by pushing the power ON/OFF button, the TE430VX motherboard
(with a power supply that supports remote power on/off) can be turned OFF from one of two
sources: the front panel power ON/OFF switch, or a “soft off” signal (coming from the Super I/O
controller) that can be controlled by the operating system. In “soft off”, an APM command issued
to the system BIOS will cause the power supply to turn OFF via the “PS ON” control signal on the
power connector. For example, Windows 95 will issue this APM command when the user clicks
on the Shutdown icon. Power can be restored by simply pressing the power ON/OFF switch at
which time the system will power back up and run POST.
1.10.12 Back Panel Connectors
The back panel provides external access to PS/2 style keyboard and mouse connectors, two USB
connectors, one parallel port, one serial port, a VGA connector, a MIDI/game port, and the external
audio jacks which are integrated on the motherboard. Figure 5 shows the general location of the
I/O connectors.

1.10.13 Add-in Board Expansion Connectors
Expansion Slots support up to four PCI and up to three ISA add-in boards. The PCI bus is fully
compliant with the PCI 2.1 specification and supports up to four bus master devices through the
four PCI connectors.
These allow the motherboard to be switched between different speeds of the Pentium processor.
These jumpers also affect the PCI and ISA clock speeds according to the following table.
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.
1.11.3 Password clear (J9C1-A, Pins 1,2,3)
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 3-5
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 1-3 position.
Default is for the password to be enabled (3-5 position).
1.11.4 CMOS Setup Access (J9C1-B, Pins 1,2,3)
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).
This jumper block changes the output of the on-board voltage regulator. Pins 2-3 should be
jumpered for processors that require standard voltage regulation, pins 1-2 should be jumpered for
processors that require the VRE specification. This jumper should not be changed by the user
unless changing to a new processor type. Some upgrade processors may require a different setting,
check the processor's documentation for the correct setting. (Standard = 3.135-3.63V,
VRE = 3.465-3.63V)
1.11.6 BIOS Recovery (J7A1)
This jumper allows the BIOS to be recovered if it has been corrupted by moving the jumper from
the 1-2 position to the 2-3 position and inserting a recovery diskette. Default setting is for normal
operation (1-2 position).

Assure that the host system, any other subassemblies such as board & drive assemblies being
added in, and internal or external wiring, are properly certified for the region(s) the end-product
will be used in. Proof of certification can be determined by the marks on the product. For
example:
Europe
The CE Marking signifies compliance with all relevant EU requirements. If the host system does
not bear the CE Marking, obtain a supplier’s Declaration of Conformity to the appropriate
standards required by the European EMC Directive and Low Voltage Directive. Other Directives,
such as the Machinery and Telecommunications Directives, may also apply depending on the type
of product. No regulatory assessment is necessary for low voltage DC wiring used internally, or
wiring used externally when provided with appropriate overcurrent protection. Appropriate
protection is achieved by max. 8 Amp current limiting circuit or a max. 5 Amp fuse or Positive
Temperature Coefficient Resistor (PTC). All Intel motherboards presently have PTC’s on all
external ports which provide DC power externally.
U.S.
For safety, a certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as
UL, CSA or ETL. External wiring must be UL Listed and suitable for the use. Internal wiring
must be UL Listed or Recognized and rated appropriately for the voltages and temperatures
involved. For electromagnetic interference, the FCC mark: Class A for commercial or industrial
only; or Class B for all applications other than described in Item 1.14.3.3 above.

3 Motherboard BIOS and Setup Utility
3.1 Introduction
The motherboard 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 motherboard also supports system BIOS shadowing,
allowing the BIOS to execute from 64-bit on-board write-protected DRAM.
Hardware has been added to the board so only Intel compiled BIOS can be flashed into the Flash
EEPROM. This was done for extended virus protection.
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 motherboard will be identified as 1.00.0x.CY0.
†
Information on BIOS functions can be found in the IBM
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
PS/2 and Personal Computer BIOS
The Intel PA28FB100BX 1 Mb Flash component is organized as 128K x 8 (128 KB). The Flash
device is divided into four areas, as described in Table 11.
Table 11. Flash Memory Organization
System AddressFLASH Memory Area

FFFFD000HFFFFDFFFH4 KB Plug and Play ESCD Storage Area
FFFFC000HFFFFCFFFH4 KB Custom LOGO and Vital Product Data
FFFE0000HFFFFBFFFH112 KB System BIOS Reserved during boot
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.
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. The user is able to
override the auto-configuration options by using the manual mode setting. The ATAPI
Specification Revision 2.5 recommends that an ATAPI device be configured as shown in the table
below.

Motherboard BIOS and Setup Utility
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 motherboard 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.
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
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 motherboard 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 Language Update Program (FLUP) 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.
NOTE
✏
A copy of “El Torito” is available on Phoenix Web page (http://www.ptltd.com/techs/specs.html).

Motherboard BIOS and Setup Utility
3.10 Flash LOGO Area
The motherboard 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 motherboard 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 Program
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 motherboard can be set to prevent user access to Setup for security purposes.
3.12.1 Overview of the Setup Menu Screens
The Setup program initially displays the Main menu screen. In each screen there are options for
modifying the system configuration. Select a menu screen by pressing the left <←> or right <→>

This section describes the options found on the Plug and Play configuration subscreen.
3.12.10.1 Configuration Mode
Sets how the BIOS gets information about ISA cards that do not have Plug and Play capabilities.
The options are Use Setup Utility and Use ICU (ISA Configuration Utility). The default is Use
Setup Utility.
If Use ICU is selected, the BIOS will depend on run-time software to ensure that there are no
conflicts between ISA boards with Plug and Play capabilities and those without. Only Boot With
PnP OS will be visible.
3.12.10.2 Boot with PnP OS
Enables the PC to boot with an operating system capable of managing Plug and Play add-in cards.
The options are None, Other, and Windows 95. The default is Windows 95.
3.12.10.3 ISA Shared Memory Size
Enables you to “unshadow” a block of the upper memory area. The options are Disabled, 16 KB,
32 KB, 48 KB, 64 KB, 80 KB, and 96 KB. The default is Disabled. If this is set to Disabled, the
ISA Shared Memory Base Address (described below) will not be visible.
Shadowing is a technique that copies a block of memory from an add-in card’s ROM to the same
address in system memory. This provides faster access and achieves higher performance. By
default, all upper memory is shadowed.
3.12.10.4 ISA Shared Memory Base Address
Sets the base address for the ISA Shared Memory. The options are C8000h, CC000h, D0000h,
D4000h, D8000h, and DC000h. The default is C8000h. This setting could affect the ISA Shared
Memory Size item. The value entered in the ISA Shared Memory Size item cannot extend to the
E0000h address. For example, if a size of 64K was selected, options D4000h, D8000h, and
DC000h will not be available.
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.
54
Motherboard BIOS and Setup Utility
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.

3.12.12.3 Set User Password
Sets the User password. The password can be up to seven alphanumeric characters.
3.12.12.4 Set Administrative Password
Sets the Administrative password. The password can be up to seven alphanumeric characters.
3.12.12.5 Unattended Start
Controls when the security password is requested. The options are Enabled and Disabled. The
default is Disabled. The User password must be enabled before you can enable this option. If
Enabled is selected, the system boots, but the keyboard will be locked until the User password is
entered.
3.12.12.6 Security Hot Key (CTRL-ALT-)
Sets a hot key that, when pressed, locks the keyboard until the User password is entered. The
Keyboard LEDs flash to indicate that the keyboard is locked. When you enter the User password,
you do not have to press the <Enter> key.
3.12.13 Exit Screen
This section describes the different ways to exit and save or not save changes made in the Setup
program.
3.12.13.1 Exit Saving Changes
Saves the changes to CMOS RAM and exits the Setup program. You can also press the <F10> key
anywhere in the Setup program to do this.
3.12.13.2 Exit Discarding Changes
Exits the Setup program without saving any changes. This means that any changes made while in
the Setup program are discarded and NOT SAVED. Pressing the <Esc> key in any of the four
main screens will do this.
