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.
