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 IrDAcompatible 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 BlasterPro compatible audio. Integrated onto the motherboard  
also is the S3Trio64V+ 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  
25/30/33 MHz  
PCI to DRAM > 100 Mbytes/sec  
Pipeline Burst SRAM  
256 or 512 KB direct-mapped  
Integrated DRAM controller  
64 bit path to memory  
Up to 4 PCI masters in addition to  
the PIIX3 and IDE  
Support for SDRAM and EDO  
DRAM  
8 MB to 128 MB main memory  
11  
 
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  
Counters/timers  
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 Windows95, 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/2keyboard/mouse connectors are located on the back panel side of the motherboard. The 5V  
lines to these connectors are protected with a PolySwitchcircuit 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  
PackardHSDSL-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 VGAspecification.

to change the screen resolution, number of colors, and large or small fonts while in Windows.  
Windows NTdrivers are embedded in the O.S.  
Graphics drivers for OS/22.11 and OS/2 WARP, MS-DOSapplications such as AutoCADand  
Microstation, and driver updates for Windows 3.11 and Windows NT may be downloaded from the  
Intel Applications Support BBS. Drivers for SCO UNIXare 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.  
15  
 
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.

1.9.2 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.

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.  
23  
 
TE430VX Motherboard Technical Product Specification  
1.10.11 Front panel Connectors  
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  
Speaker Reset Sleep LED  
HD LED  
Infrared  
Sleep Pwr On  
OM04524  
Figure 4. Front Panel I/O Connectors  
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.  
24  
 
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  
25  
 
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).

TE430VX Motherboard Technical Product Specification  
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).

1.15.4 Installation Requirements  
CAUTION  
To avoid an adverse impact on the compliance with safety or regulatory requirements due to  
installation of this board assembly, the following guidelines must be followed.  
1.15.4.1 Follow Installation Instructions  
Be sure to read and adhere to all of these instructions, and the instructions supplied with the host  
system and associated modules. If the instructions of the host system appear to be incompatible  
with these instructions or the instructions of any associated modules, contact the suppliers’  
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  
This product was evaluated for use in systems installed in offices, homes, schools, computer rooms  
or similar applications. Other applications, such as medical, industrial, alarm systems and test

33  
 
TE430VX Motherboard Technical Product Specification  
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.  
34  
 
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 IBMPS/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.

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.

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  
CompuServeby 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 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.  
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.
