3.2.4 ICH3-S
The ICH3-S is a multi-function device, housed in a 421-pin BGA device, providing a HI 1.5 to
PCI bridge, a PCI IDE interface, a PCI USB controller, and a power management controller.
Each function within the ICH3-S has its own set of configuration registers. Once configured,
each appears to the system as a distinct hardware controller sharing the same PCI bus
interface.

On the SE7501WV2 server board, the primary role of the ICH3-S is to provide the gateway to all
PC-compatible I/O devices and features. The SE7501WV2 server board uses the following
