INTRODUCTION
The ATX GX1 Dual-P mainboard is a state-of-the-art dual-processor server
mainboard based on Intel®Pentium®II XeonTM processor. The Intel®
Pentium®II XeonTM processor is designed exclusively for powerful servers
and workstations.
The mainboard uses the highly integrated Intel®82440GX chipset to support
the PCI/ISA and Green standards, and to provide the Host/AGP bridge. The
82371EB chipset integrates all system control functions such as ACPI
(Advanced Configuration and Power Interface). The ACPI provides more
Energy Saving Features for the OSPM(OS Direct Power Management)
function. The Intel®82371EB chipset also improves the IDE transfer rate by
supporting Ultra DMA/33 IDE that transfers data at the rate of 33MB/s.
The mainboard also supports the System Hardware Monitor Controller as an
optional function. This function includes: CPU /power supply/chassis fan
revolution detect, CPU/system voltage monitor, system temperature monitor,
and chassis intrusion detect.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel®Pentium®II XeonTM processor.The
mainboard uses a CPU Slot called Slot 2 for easy CPU installation and a DIP
switch (SW1) to set the proper speed for the CPU. The CPU should always
have a Heat Sink attached to prevent overheating.

2.1-2 CPU Core Speed Derivation Procedure
The DIP Switch SW1 (1, 2, 3, and 4) is used to set the Core/Bus (Fraction)
ratio of the CPU. The actual core speed of the CPU is the Host Clock
Frequency multiplied by the Core/Bus ratio. For example:
If CPUClock = 100MHz
Core/Bus ratio = 4.5
then CPU core speed = Host Clock x Core/Busratio
= 100MHzx4.5
= 450MHz
