Handling Precautions
Warning :
1. Static electricity may cause damage to the integrated circuits on the
mainboard.
Before handling any mainboard outside of its protective packaging,
ensure that there is no static electric charge in your body.
2. There is a danger of explosion if the battery is incorrectly replaced.
Replace only with the same or an equivalent type recommended by the
manufacturer.
3. iscard used batteries according to the manufacturer’s instructions.
Observe the following basic precautions when handling the mainboard or other
computer components:
nWear a static wrist strap which fits around your wrist and is connected to a
natural earth ground.
nTouch a grounded or anti-static surface or a metal fixture such as a water
pipe.
nAvoid contacting the components on add-on cards, boards and modules and
with the “gold finger” connectors plugged into the expansion slot. t is
best to handle system components by their mounting bracket.
The above methods prevent static build-up and cause it to be discharged
properly.

Overview
Based on the new highly-integrated VIA 580VPX, the mainboard combines
blistering PentiumÒ processor per ormance with support or intelligent
diagnostic and power management eatures to provide a power ul and versatile
plat orm.
With its switching voltage regulator, the VA-502 runs a complete range o Intel
PentiumÒ processors, including the Intel Pentium processor with MMXÔ
technology, as well as the AMD-K5Ô and Cyrix/IBM 6x86Ô, and is easily
upgradable to the Cyrix/IBM MXÔ and the AMD-K6Ô. For added power and
per ormance, the VA-502 takes up to 512KB Pipeline Burst Level II cache and
up to 512MB DRAM via our 72-pin SIMM sockets and two 168-pin DIMM
sockets which accept high-speed EDO, and lightning- ast SDRAM memory
types.
The VA-502 comes with a ull set o I/O eatures conveniently integrated on the
rear I/O panel, including two USB connectors. The board also has an integrated
PCI Bus Master Enhanced IDE controller with support or the new Ultra
DMA/33 protocol, which doubles ATA-2 Hard Disk Drive data trans er rates to
33MB/s while maintaining ull backwards compatibility with existing PIO Mode
3, PIO Mode 4 and DMA Mode 2 devices.
Chapter 1 o this manual gives you a brie overview o the VA-502 mainboard,
including its main components and eatures. Chapter 2 contains advice on how
to upgrade and install key components on the mainboard, while Chapter 3
provides detailed in ormation about the board’s BIOS settings. For the most up-
to-date in ormation about your mainboard and the latest FAQs and BIOS
updates, visit FIC Online at www. ic.com.tw.

VA-502 Mainboard Manual
Advanced Features
This mainboard comes equipped with the most advanced new eatures that not
only optimize the per ormance o the latest processors but also enhance the
manageability, power management capabilities, and user- riendliness o your
system. This section provides detailed in ormation on these eatures, and how
they are implemented on the mainboard.
nOptimized Intel MMXÔ Performance
The mainboard utilizes the advanced eatures o the VIA 580VPX to
optimize the unrivaled per ormance o the Intel PentiumÒ processor with
MMXÔ technology, allowing you to enjoy a richer video, audio, digital
imaging and communications experience rom the latest generation o
multimedia so tware. To provide you with additional lexibility, the
mainboard also supports other leading-edge processors eaturing Intel’s
MMXÔ technology, including the AMD-K6Ô processor.
nLightning-Fast SDRAM Performance
The mainboard supports the new generation o lightning- ast SDRAM
(Synchronous Dynamic Random Access Memory) via its two onboard 168-
pin DIMM sockets. SDRAM delivers an added boost to overall system
per ormance by increasing the CPU-to-memory data trans er rate to
528MB/sec compared to 264MB/sec or conventional EDO DRAM.
SDRAM per ormance on the VA-502 is urther boosted by the board’s
integrated I2C controller, which optimizes the memory timing settings.
nBlistering Ultra DMA/33 HDD Performance
With its integrated Enhanced PCI Bus Master IDE controller that supports
the new Ultra DMA/33 protocol, this mainboard doubles HDD data trans er
rates to 33MB/sec, compared to 16MB/sec or conventional PIO Mode 3,
PIO Mode 4, and DMA Mode 2 devices. By reducing the CPU’s workload
and increasing CPU utilization, Ultra DMA/33 signi icantly improves
system per ormance when running applications under WindowsÒ 95 and
WindowsÒ NT environments. The Ultra DMA/33 protocol is completely
backward compatible with conventional ATA-2 HDD devices; so the
mainboard also supports existing PIO Mode 3, PIO Mode 4 and DMA
Mode 2 devices using the same cable.
6
Overview
With the integrated Enhanced PCI Bus Master IDE controller you can
connect up to our Enhanced IDE peripheral devices to your system. All
devices are categorized in the same way that IDE hard disks were
con igured in the past, with one device set as the master device and the
other as the slave device. We recommend that Hard Disk Drives use the
primary IDE connector and that CD-ROM Drives utilize the secondary IDE
connector or optimum system per ormance.
nfrared ( R) Connections
This mainboard eatures support or highly-sophisticated SIR technology, which
allows bi-directional and cordless data transactions with other IrDA compliant
computers and peripheral devices using in rared as a medium. This transmission
is carried out in either Full Duplex Mode or Hal Duplex Mode. The ormer
allows simultaneous data transmission and reception, while the latter disables
the reception when transmission occurs.
The I/O chipset on this mainboard eatures a SIR inter ace that is ully
compliant with the IrDA standard. An IrDA device can be installed via a 9-pin
D-type connector in the rear panel o the computer which is linked by a cable
to the onboard IrDA pinhead.
The serial port COM2 on this mainboard is designed to be a SIR compliant
port. I you wish to install the SIR connection eature, you need to adjust the
BIOS option or high-speed per ormance.

VA-502 Mainboard Manual
Universal Serial Bus (USB) Functionality
This mainboard eatures integrated support or state-o -the-art USB technology,
which provides high-speed and easy-to-use Plug & Play connections to the
uture generation o external peripherals, such as keyboards, mouse, monitors,
game devices, scanners, printers, and ax/modems.
USB overcomes conventional I/O bottlenecks by combining the I/O ports into a
single dual-channel connector. For optimum ease o use and lexibility, USB not
only allows the automatic detection and con iguration o peripherals a ter
installation, but also enables the simultaneous connection.
This mainboard eatures an optional USB riser card (see the photo below) with
bracket that can be installed in one o the I/O expansion slots on the rear panel
o the system, as shown in the illustration below. It provides ast and convenient
Plug and Play peripheral connections outside your computer, allowing you take
ull advantage o the universal unctionality and lexibility o USB technology.
