INTRODUCTION
The ATX mainboard is a high-performance personal computer mainboard
based on the Intel® Socket 370 processor and Cyrix® processor. The Intel®
Socket 370 processor supports MMXTM (Multimedia Extension) technology.
The mainboard uses the highly integrated VIA VT82C693A chipset to
support to provide the Host/AGP bridge. The VIA VT82C596B chipset
integrates all system control functions such as ACPI (Advanced Configura-
tion and Power Interface). The ACPI provides more Energy Saving Features
for the OSPM(OS Direct Power Management) function. The VIA VT82C596B
chipset also improves the IDE transfer rate by supporting Ultra DMA/33/66
IDE that transfers data at the rate of 33/66MB/s.
The mainboard also supports the System Hardware Monitor Controller. Its
functions include: CPU /power supply/chassis fan revolution detect, CPU/
system voltage monitor, chassis intrusion detect and TOP TECH III as an
optional function.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel® CeleronTM or Pentium® III processor.
The mainboard uses a CPU socket called Socket 370 for easy CPU installa-
tion. The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.
2.1-1 CPU Installation Procedures
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.
3. Press the lever down to
complete the installation.

2.1-2 CPU Core Speed Derivation Procedure (SW1)
1. If the CPU Core/Bus ratio is already fixed, adjusting the SW1 will not
change the CPU Core/Bus ratio. If the Core/Bus ratio is not fixed by the
CPU, then you can adjust the SWI to change the Core/Bus ratio.
