assigns PCI bus numbers. Function 1 initializes all static devices that include manual

configured onboard peripherals, memory and I/O decode windows in PCI-PCI bridges, and

noncompliant PCI devices. Static resources are also reserved. Function 2 searches for

and initializes any PnP, PCI, or AGP video devices.

38 Initialize different buses and perform the following functions: Boot Input Device Initialization

devices. Function 5 configures all onboard peripherals that are set to an automatic

configuration and configures all remaining PnP and PCI devices.
