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 MMXTM(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).

SW1 CPU
CPU Core Speed Derivation Procedure
1. The DIP Switch SW1 (4 & 5) is used to adjust the CPU clock frequency.
2. 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 CPU Clock = 66MHz
Core/Bus ratio = 1.5
then CPU core speed = Host Clock x Core/Bus ratio
= 66MHz x 1.5
= 100MHz
3. The PCI Bus Clock is fixed at 33MHz.
SW1 CPU
Note: It is best to set the clock at 100MHZ.
For it will adjust itself to 66MHz if needed.

Avoid clearing the CMOS while the system is on; it will damage the mainboard.

Power On Mode Jumper: JP2
The mainboard supports two kinds of system boot up: the Boot-Up by switch and the Immediate Boot-Up.
With the Boot-Up by Switch, the system will boot up only when the power on switch is pressed. For
Immediate Boot-Up, the system will boot up instantly when the power connector is connected into the system.

Floppy Disk Connector: FDC
The mainboard also provides a standard floppy disk connector FDC that supports 360K, 720K, 1.2M, 1.44M
and 2.88M floppy disk types. This connector supports the provided floppy drive ribbon cable.

Connectors
Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE Controller that provides PIO mode 0~4, Bus Master, and Ultra
DMA/33 function. It has two HDD connectors IDE1 (primary) and IDE2 (secondary). You can connect up to
four hard disk drives, CD-ROM, 120MB Floppy (reserved for future BIOS) and other devices to IDE1 and
IDE2. These connectors support the provided IDE hard disk cable.
IDE1(Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master and a Slave drive. You
must configure second hard drive to Slave mode by setting the jumper accordingly.
IDE2(Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
