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:
BIOS
The settings in the BIOS Setup utility are not retained
Replace the CMOS battery. For instructions, see 
Checkpoint
Description
2A
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.
38
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.
Checkpoint
Description
AC
First ASL checkpoint. Indicates that the system is 
running in ACPI mode.
AA
System is running in APIC mode.
01, 02, 03, 04, 05
Entering sleep state S1, S2, S3, S4, or S5.
10, 20, 30, 40, 50
Waking from sleep state S1, S2, S3, S4, or S5.
