1.1 Features and Specifications
1.1.1 Features
Chipset
•Intel82430TX PCIset chipset
Processor
The system board is equipped with a 321-pin ZIF socket (Intel
Socket 7). This socket is designed for easy removal of an old
processor and easy insertion of an upgrade processor. The system
board is also equipped with a switching voltage regulator that
supports 2.8V to 3.5V core voltage for various processors.
•Intel Pentiumprocessor with MMXTM technology-166/200/
233MHz
•Intel Pentium90/100/120/133/150/166/200MHz
•Cyrix6x86L PR150+/PR166+ and 6x86MX-PR166/PR200
•AMDK5 PR90/PR100/PR120/PR133/PR166
•AMDK6-166, K6-200, K6-233 and future K6 processors
System Memory
The system board supports 8MB to 256MB of memory. It is
equipped with two DIMM and four SIMM sockets. The 168-pin
DIMM sockets use x64 EDO (60/70ns), fast page mode (60/70ns),
or SDRAM (10/12/13ns), 3.3V. The 72-pin SIMM sockets use EDO
or fast page mode, 60/70ns, x32 DRAM, 5V.
Level 2 Cache Memory
•512KB pipeline burst, direct map write-back cache installed on
the system board.
Expansion Slots
The system board is equipped with 4 dedicated PCI slots and 3
dedicated 16-bit ISA slots. All PCI and ISA slots are bus masters.

Desktop Management Interface (DMI)
The system board comes with DMI 2.0 built into the BIOS. The
DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in
the DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier.
Onboard I/O
•Two NS16C550A-compatible serial ports
•One SPP/ECP/EPP parallel port
•One floppy drive interface supports up to 2.88MB floppy
drives.
•One PS/2 mouse port
•One PS/2 or AT keyboard port
•One 12-pin standard AT power supply connector
PCI Bus Master IDE Controller
•Two PCI IDE interfaces support up to four IDE devices
•Ultra DMA/33 supported (Synchronous DMA mode - data
transfer rate up to 33MB/sec.)
•PIO Mode 3 and Mode 4 Enhanced IDE (data transfer rate up
to 16.6MB/sec.)
•Bus mastering reduces CPU utilization during disk transfer
•ATAPI CD-ROM supported
•LS-120 and ZIP supported
IrDA Interface
The system board is equipped with an IrDA connector for
wireless connectivity between your computer and peripheral
devices.
USB Ports
The system board is equipped with a header for external USB
ports. USB allows data exchange between your computer and a
wide range of simultaneously accessible external Plug and Play
peripherals.

BIOS
•Award BIOS, Windows95 Plug and Play compatible
•Flash EPROM for easy BIOS upgrades
Power Supply Connector
The system board is equipped with an AT power supply connector
for connecting an AT power supply.
1.1.2 Technology
SDRAM
Synchronous Dynamic Random Access Memory (SDRAM) is a
DRAM technology that uses the clock on the chip to synchronize
with the CPU clock so that the timing of the memory chips and
the timing of the CPU are synchronized. This saves time during
transmission of data, subsequently increasing system performance.
Ultra DMA/33 Bus Master IDE
The system board supports Synchronous Ultra DMA mode that
provides data transfer rate at 33MB/sec, which is double the data
transfer rate of Enhanced IDE or ATA-2. This enables the CPU to
operate more efficiently when handling simultaneous events.
1.1.3 Intelligence
RTC Timer to Power On the System
The RTC installed on the system board allows your system to
automatically wake up on the set day and time. Set the day and
time you would like your system to power on in the “Resume By
Alarm” field (Power Management Setup) of the Award BIOS.

Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table
of your hard disk drive. If an attempt is made to write to the
boot sector or partition table of the hard disk drive, the BIOS will
halt the system and an error message will appear. Refer to the
“Virus Warning” field in the BIOS Features Setup section of this
manual (Chapter 3).
