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.

10

Motherboard Description

1.5.1.2 SDRAM

Synchronous Dynamic Random Access Memory, (SDRAM) is designed to improve main memory
performance. SDRAM is synchronous to the memory clock unlike standard Fast Page DRAM, or
EDO DRAM. All the timing is dependent on the number of memory clock cycles. This makes the
timing design simpler and makes a faster memory speed easier to achieve. Discrete SDRAM
components must meet the 66 MHz PC SDRAM Specification version 1.0 to function correctly.

1.5.2 Second Level Cache

The Pentium processor's internal cache can be complemented by a second level cache using high­performance Pipelined Burst SRAM with GWE (Global Write Enabled) or Asynchronous Cache.

One factory option is an integrated 256 KB direct mapped write-back second level cache
implemented with two 32k x 32 Pipeline Burst SRAM devices that take advantage of the Global
Write Enable pin. A 5v 8 KB x 8 external Tag SRAM provides caching support for up to 64 MB
of system memory.

A second factory option is a Type 1 CELP connector, specified by Intel’s COAST Module
Specification version 3.0. The Type 1 CELP connector has a keying “hip” located at one end of
the connector. This connector allows the use of both a GWE PBSRAM COAST module, and a
GWE Asynchronous COAST module. The GWE Asynchronous modules must be built for Intel’s
82430VX designs and are not interchangeable with Asynchronous modules built for 82430FX
designs. The reason for this incompatibility is the additional logic added to the 82430VX modules
to account for the GWE functionality built into the chipset.

1.6 Chipset

The Intel 82430VX PCIset consists of the 82430VX System Controller (TVX), two Data Paths
(TDX) and one 82371SB PCI ISA/IDE Xcelerator (PIIX3) bridge chip.

1.6.1 82430VX System Controller (TVX)

The 82430VX TVX provides all control signals necessary to drive a second level cache and the
DRAM array, including multiplexed address signals. The TVX also controls system access to
memory and generates snoop controls to maintain cache coherency. The TVX comes in a 208-pin
QFP package that features:

• CPU interface control

• Integrated L2 write-back cache

 8 MB to 128 MB main memory

• Fully synchronous PCI bus interface
 25/30/33 MHz
 PCI to DRAM > 100 Mbytes/sec
 Up to 4 PCI masters in addition to

the PIIX3 and IDE

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
 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

• PCI 2.1 compliance

• Enhanced fast DMA controller

• Interrupt controller and steering

• Counters/timers

• SMI interrupt logic and timer with

fast on/off mode

1.6.4 IDE SUPPORT

The motherboard provides two independent bus-mastering PCI IDE interfaces that support PIO
Mode 3 and Mode 4 devices. The system BIOS supports Logical Block Addressing (LBA) and
Extended Cylinder Sector Head (ECHS) translation modes as well as ATAPI (e.g. CD-ROM)
devices on both IDE interfaces. The system BIOS automatically detects IDE device transfer rate
and translation mode.

Normally, programmed I/O operations require a substantial amount of CPU bandwidth. In true
multi-tasking operating systems like Windows
mastering IDE can be used to complete other tasks while disk transfers are occurring. When used
in conjunction with the appropriate driver for the Windows 95 environment, the IDE interface can
operate as a PCI bus master capable of supporting PIO Mode 4 devices with transfer rates of up to
16 MB/sec.

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
healing fuse, re-establishing the connection after an over-current condition is removed. While this
device eliminates the possibility of having to replace a fuse, care should be taken to turn off the
system power before installing or removing a keyboard or mouse. The system BIOS can detectand
correct keyboards and mice plugged into the wrong PS/2 style connector.

The integrated 8042 microcontroller contains the AMI Megakey keyboard/mouse controller code
which, besides providing traditional keyboard and mouse control functions, supports Power­On/Reset (POR) password protection. The POR password can be defined by the user via the Setup
program. The keyboard controller also provides for the following "hot key" sequences:

• <CTRL><ALT><DEL>: System software reset. This sequence performs a software reset of
the system by jumping to the beginning of the BIOS code and running the POST operation.

• <CTRL><ALT><+> and <CTRL><ALT><->: Turbo mode selection. <CTRL><ALT><->
sets the system for de-turbo mode, emulating an 25 MHz AT, and <CTRL><ALT><+> sets
the system for turbo mode. Changing the Turbo mode may be prohibited by an operating
system, or when the CPU is in Protected mode or virtual x86 mode under DOS.

• <CTRL><ALT><defined in setup>: A power down hot-key sequence takes advantage of the
SMM features of the Pentium Processor to greatly reduce the system’s power consumption
while maintaining the responsiveness necessary to service external interrupts. A security hot­key sequence provides password protection to the system.

1.7.3 Real time clock, CMOS RAM and battery

The integrated Real Time Clock (RTC) is DS1287 and MC146818 compatible and provides a time
of day clock, 100-year calendar with alarm features. The RTC can be set via the BIOS SETUP
program. The RTC also supports 242-byte battery-backed CMOS RAM in two banks which is
reserved for BIOS use. The CMOS RAM can be set to specific values or cleared to the system
default values using the BIOS SETUP program. Also, the CMOS RAM values can be cleared to
the system defaults by using a configuration jumper on the motherboard.

An external coin-cell style battery provides power to the RTC and CMOS memory. The battery
has an estimated lifetime of three years if the system is not plugged into the wall socket. When the
system is plugged in, power is supplied from the ATX power supply’s 5v standby current to extend
the life of the battery.

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
transfers at 115kbps from a distance of 1 meter.

1.7.5 Consumer IR Support

The motherboard also has a signal pin to support Consumer IR devices(remote controls). A
software and hardware interface is required to implement consumer IR on with the motherboard.

1.7.6 Parallel port

A 25-pin D-Sub header is provided on the back panel for a multi-mode bi-directional parallel port.
The parallel port operates in standard mode, Enhanced Parallel Port (EPP) version 1.7 mode, with
BIOS and Driver support, and a high speed Extended Capabilities Port (ECP) compatible mode.
EPP Mode requires a driver provided by the peripheral manufacturer to operate correctly.

1.8 Graphics Subsystem (S3 Trio64V+)

The motherboard is available with an S3 Trio64 V+ SVGA graphics controller with 1 MB of
graphics memory upgradeable to 2 MB. The graphics DRAM can be upgraded to 2 MB by
installing two 256 KB x 16 SOJ memory devices in the provided sockets. The Trio64 V+ has a
64-bit graphics engine and incorporates the S3 Streams Processor that enables the device to convert
YUV formatted video data to RGB and provides acceleration for scaling the video display without
compromising picture quality or frame rate. The on-chip RAMDAC/clock synthesizer is capable
of output pixel data rates of 135 MHz providing non-interlaced screen resolutions of up to
1280x1024x256 colors at 75 Hz with 2 MB of DRAM. Hardware acceleration for graphics
functions such as BitBLTs with ROPs, 2-point line draws, trapezoidal and polygon fills, clipping
and cursor support provide high performance operation under Windows and other GUI
environments. In addition, a fast linear addressing scheme based upon DCI reduces software
overhead by mapping the display memory into the CPU’s upper memory address space and
permitting direct CPU access to the display memory.

†

. The IrDA specification provides for data

The motherboard supports the 26-pin VESA feature connector for synchronizing graphics output
with an external NTSC or PAL signal and a shared frame buffer interface to maximize multi-media
performance. Boards configured with the Trio64 V+ will have a 34 pin feature connector that
supports the VESA requirements as well as the LPB (Local Peripheral Bus) that provides a glueless
bi-directional interface to a video companion device such as an MPEG/live video decoder. The
motherboard also supports other VESA standards such as the VESA DPMS protocol to put a
DPMS compliant monitor into power savings modes and the VESA Display Data Channel
(DDC2B) that permits transfer of monitor identification and resolution support data for ease of use.
When a monitor is not plugged into the system on power-up, the video will default to color mode,

†

rather than monochrome. This is a deviation from the VGA

14

specification.

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.

1.9.2 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.
