DIM code checkpoints
The Device Initialization Manager (DIM) gets control at various times during BIOS POST to initialize
different system buses. The following table describes the main checkpoints where the DIM module
is accessed.
ACPI runtime checkpoints
ACPI checkpoints are displayed when an ACPI-capable operating system either enters or leaves a
sleep state. The following table describes the types of checkpoints that may occur during ACPI sleep
or wake events:

Description
Initialize different buses and perform the following functions:
Reset, Detect, and Disable (function 0) — Disables all device
■
nodes, PCI devices, and PnP ISA cards. It also assigns PCI
bus numbers.
Static Device Initialization (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.
Boot Output Device Initialization (function 2) — Searches
■
for and initializes any PnP, PCI, or AGP video devices.
Initialize different buses and perform the following functions:
Boot Input Device INitialization (function 3) — Searches for
■
and configures PCI input devices and detects if system has
standard keyboard controller.
IPL Device Initialization (function 4) — Searches for and
■
configures all PnP and PCI boot devices.
General Device Initialization (function 5) — Configures all
■
onboard peripherals that are set to an automatic
configuration and configures all remaining PnP and PCI
devices.
