1 Motherboard Description

1.1 Overview

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 socket provides upgrades to future 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

16C provides 16-bit stereo, Sound Blaster^†Pro compatible audio. Integrated onto the motherboard

also is the S3^†Trio64^†V+ video subsystem. Up to four PCI local bus slots provide a high

bandwidth data path for data-movement intensive functions such as video or networking, and up to

three ISA slots complete the I/O mix. A total of six expansion slots may be populated with full

length add-in cards: one PCI and ISA slot share the same chassis I/O panel.

TE430VX Motherboard Technical Product Specification

1.4 Microprocessor

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 high-

performance 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

controller

•

Fully synchronous PCI bus interface

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

•

PCI 2.1 compliance

Enhanced fast DMA controller

Interrupt controller and steering

SMI interrupt logic and timer with

fast on/off mode

•

PIO Mode 4 transfers up to

16 MB/sec

Integrated 8 x 32-bit buffer for

bus master PCI IDE burst

transfers

Bus master 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^†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.

Motherboard Description

1.7 Ultra I/O Interface Controller (SMC FDC37C93FR)

1.7.1 Floppy controller

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^†circuit which 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, 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 Power-

On/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 hot-

key 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.

TE430VX Motherboard Technical Product Specification

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. 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^†. The IrDA specification provides for data

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 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,

rather than monochrome. This is a deviation from the VGA^†specification.

1.8.2 Graphics Drivers and Utilities

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.

Windows NT^†drivers are embedded in the O.S.

Graphics drivers for OS/2^†2.11 and OS/2 WARP, MS-DOS^†applications such as AutoCAD^†and

Microstation, and driver updates for Windows 3.11 and Windows NT may be downloaded from the

Intel Applications Support BBS. Drivers for SCO UNIX^†are available from SCO.

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.

TE430VX Motherboard Technical Product Specification

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.

1.10.10 Power Supply Connectors

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.

1.10.11.1 Speaker

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

TE430VX Motherboard Technical Product Specification

1.10.11.7 Remote ON/OFF and Soft Power Support

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.

1.11.2 Clear CMOS (J9C1-A, Pins 4,5,6)

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.

1.11.3 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).

1.11.5 CPU Voltage (J6M1)

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).

technical support organizations for the products involved to determine the appropriate action for

continued safety and regulatory compliance of the resultant system. Failure to read and follow

instructions provided by host system and module suppliers may result in increased safety risk and

non-compliance with regional laws and regulations.

1.15.4.2 Assure Host System Compatibility

For electromagnetic compatibility, the host system enclosure and power supply should have passed

electromagnetic compatibility testing using a board with a microprocessor from the same family as

the microprocessor on this board, operating at the same or higher microprocessor speed. Also,

only peripherals (computer input/output devices, terminals, printers, etc.) that are CE Marked and

certified by the FCC to comply with Class B limits may be attached to this board. Pay particular

attention to the installation instructions of the host system and other modules, particularly

concerning certifications, external I/O cable shielding and filtering, mounting, grounding and

bonding requirements to assure appropriate shielding effectiveness. Otherwise electromagnetic

compatibility testing must be repeated on a representative sample of the complete system.

For safety, if mismating of connectors could result in a hazard, assure that all connectors are

sufficiently keyed to prevent mismating.

1.15.4.3 Use Only In Intended Applications

1.15.4.4 Assure Host System & Accessory Certifications

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.

Canada

For safety, a nationally recognized certification mark such as CSA or cUL. 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.

1.15.4.5 Installation Precautions

During installation and initial test, use caution to avoid personal injury and damage to wiring due

to sharp pins on connectors and printed circuit assemblies, rough chassis edges and corners, and

hot components. Adhere to warnings and limitations regarding accessibility into areas designated

only for authorized technical personnel.

Motherboard Description

1.15.4.6 Battery Marking

There is insufficient space on this board product to provide the required replacement and disposal

instructions for the battery. The following marking must be placed permanently and legibly on the

host system as near as possible to the battery:

CAUTION

Danger of explosion if battery is incorrectly replaced

Replace with only the same or equivalent type recommended by the manufacturer. Dispose of used

batteries according to the manufacturer’s instructions.

1.15.4.7 Overload Protection:

Unless the power supply is provided with inherent overcurrent protection, use caution to avoid

overloading the power supply output. This can be accomplished by assuring that the calculated

total current load of all the modules within the system is less than the output current rating of the

power supply. Failure to accomplish this could result in overheating in the power supply, which

could result in a fire or could cause damage to insulation separating hazardous AC line circuitry

from low-voltage user accessible circuitry. If the load drawn by a particular module cannot be

determined by the markings and instructions supplied with the module, contact the module

supplier’s technical support organization.

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^†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). The Flash

device is divided into four areas, as described in Table 11.

TE430VX MotherboardMotherboard Technical Product Specification

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.

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

CompuServe^†by typing Go PlugPlay.

TE430VX MotherboardMotherboard Technical Product Specification

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 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 <→>

arrow keys. Use the up <↑> or down <↓> arrow keys to select items in a screen. Use the <Enter>

key to select an item for modification. For certain items, pressing <Enter> will bring up a

subscreen. After you have selected an item, use the arrow keys to modify the setting.

3.12.10 Plug and Play Configuration Subscreen

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.

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.
