Specification & User’s Guide
1. Introduction
The MSI ATX BX2 mainboard is a high-performance personal computer mainboard
based on the Pentium
®
II processor. The Pentium
®
II processor supports MMX
TM
(Multime-
dia Extension) technology.
The mainboard uses the highly integrated Intel
®
82443BX AGP chipset to support
the PCI/ISA and Green standards, and to provide the Host/AGP bridge. The Intel
®
82371AB chipset integrates all system control functions such as ACPI (Advanced Configu-
ration 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 LM78 System Hardware Monitor Controller as an
optional function. The LM78 function includes: CPU /power supply/chassis fan revolution
detect, CPU/system voltage monitor, system temperature monitor, and chassis intrusion
detect(optional).
