MSI ATX BX7, MS-6147 User Manual

CHAPTER 1 INTRODUCTION
1-1
The MICRO A TX BX7 mainboard is a high-performance personal computer mainboard based on the Intel® Pentium® II processor. This mainboard combines leading edge AGP A TI® 3D RAGE PRO/RAGE PRO Turbo technol­ogy in graphics and Creative® ES1371/ES1373(reserved) PCI technology in audio. The Intel® Pentium® II processor supports MMX
TM
(Multimedia
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® 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. Its functions include: CPU /power supply/chassis fan revolution detect, CPU/system voltage monitor, system temperature monitor , and chassis intrusion detect(optional).

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel® Pentium® II/CeleronTM processor. The mainboard uses a CPU Slot called Slot 1 for easy CPU installation and a jumper switch (SW1) to set the proper speed for the CPU. The CPU should always have a Heat Sink and a cooling fan attached to prevent overheating.

1 . 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/100MHz
Core/Bus ratio = 4
then CPU core speed = Host Clock x Core/Bus ratio
= 66MHz x 4/100MHz x 4 = 266MHz/400MHz

Note: The CPU Bus Frequency is set at 66MHz or 100MHz by CPU
default.

To adjust the speed of the CPU, you must know the specification of your CPU (always ask the vendor for CPU specification). The mainboard can auto-detect between 66 or 100MHz CPU Bus Frequency .

2.1-4 Fan Power Connectors: CPUFAN/PSFAN/SYSFAN
These connectors support system cooling fan with +12V. It supports three pin head connector. When connecting the wire to the connector, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If your mainboard has System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2 pulses. System Hardware Monitor will count and report the fan rotation speed.

The mainboard supports a maximum memory size of 256MB (8M x 8) or 512MB (16M x 4) registered DIMM for SDRAM: It provides two 168-pin unbuffered DIMMs (Double In-Line Memory Module) sockets. It supports 8 MB to 256 Mbytes DIMM memory module.
DIMM1(Bank0 + Bank1)
DIMM2(Bank2+ Bank3)
There are two kinds of DIMM specification supported by this mainboard: PC100 and PC66. If you use
66MHz CPU Bus Frequency, these two DIMM Specs. is supported. If you use 100 MHz CPU Bus Frequency, only PC100 DIMM Specs. is supported.
