Chipset; Serverworks Cnb30Le North Bridge Chip - Intel SRMK2 - Server Platform - 0 MB RAM Technical Specifications

3.4 Chipset

®
The ServerWorks ServerSet
Bridge chip and the ServerWorks OSB4 South Bridge chip. The CNB30LE provides an optimized
DRAM controller. The I/O subsystem of the ServerWorks chipset is based on the OSB4 South
Bridge, which is a highly integrated PCI ISA IDE Xcelerator Bridge.
