MS-6119 ATX BX2 Mainboard
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 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 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).
