Introduction
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
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.
