Checkpoint 2A Description 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. 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 38 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. AC First ASL check point.

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.
AC
First ASL check point. Indicates 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.
