Introduction 1
The MS-6377 ATX mainboard is a high-performance computer
mainboard based on RCC/ServerWorks chipset. The MS-6377 is designed
for dual Intel®Pentium®III (FC-PGA) processor for cost-effective entry-
level and mid-range server markets.
The mainboard consists of the North Bridge “CNB30 LE” and
ServerWorks Open South Bridge™ “OSB4”. CNB30 LE provides an inte-
grated high-performance main memory sub-system, a dual channel PCI bus,
and a 32-bit PCI Bus. The CNB30 LE filters all the unnecessary bus traffic
going to the Processor bus and also performs packing and unpacking of
data for PCI accesses, which in turn allows more Processor bus bandwidth
for other processors in multiprocessor systems. As a main memory sub-
system, the CNB30 LE provides an efficient interface between the Processor
bus and memory with data integrity features such as ECC, memory
scrubbing, and memory snarfing.
OSB4 primarily functions as a PCI to ISA bridge, but is also a source
of numerous other integrated functions, including ISA bus controller,
DMA33 support, ACPI, USB interface, etc.
This chapter includes the following topics:

PC Alert™ III
The PC AlertTM III is an utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can detect the following PC hardware
status during real time operation:
* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion
If one of the items above is abnormal, the program main screen will be immedi-
ately shown on the screen, with the abnormal item highlighted in red. This will
continue to be shown,until user disables the warning.
Note: Items shown on PC Alert III vary depending on your system’s status.

Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the compo-
nents and follow the installation procedures. For some components, if you
install in the wrong orientation, the components will not work properly.
Use a grounded wrist strap before handling computer components.
Static electricity may damage the components.

Central Processing Unit: CPU
The mainboard supports Single/Dual Intel®Coppermine processor
(s). The mainboard uses two CPU sockets called Socket 370 for easy CPU
installation. You can install SINGLE or DUAL CPUs on the board to meet
your own needs. Keep the following points in mind before installing CPU(s):
1. If SINGLE CPU is intended, always install the CPU on the CPU1
socket.
2. To install DUAL CPUs on the board, you must use the same type of
CPUsrunningat the same FSB frequency.
When you are installing the CPU, make sure the CPU has a Heat
Sinkanda cooling fan attached onthetop to prevent overheating. If you do
not find the Heat Sink and cooling fan, contact your dealer to purchase and
install them before turning on the computer.
