Checkpoint Description
2A
Initialize different buses and perform the following functions:
Reset, Detect, and Disable (function 0); Static Device
Initialization (function 1); Boot Output Device Initialization
(function 2). Function 0 disables all device nodes, PCI devices,
and PnP ISA cards. It also 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 (function 3); IPL Device
Initialization (function 4); General Device Initialization (function
5). Function 3 searches for and configures PCI input devices
and detects if system has standard keyboard controller.
Function 4 searches for and configures all PnP and PCI boot
devices. Function 5 configures all onboard peripherals that are
set to an automatic configuration and configures all remaining
PnP and PCI devices.
The Device Initialization Manager (DIM) gets control at various times during
BIOS POST to initialize different system busses. The following table describes
the main checkpoints where the DIM module is accessed
