Motherboard Description
1-6.1 The Intel® 815EP B-step Chipset System
The Intel® 815EP B-step Chipset uses a hub architecture with the
Intel® 815EP B-step MCH as the host bridge hub and the 82801BA
I/O Controller Hub2(ICH2) as the I/O hub. The ICH2 is a highly
integrated multifunctional I/O Controller Hub that provides the
interface to the PCI Bus and integrates many of the functions needed
in today's PC platforms. The Intel® 815EP B-step MCH and ICH2
communicate over a dedicated hub interface.
