Checkpoint Description
0E
Testing and initialization of different Input Devices. Also, update the Kernel
Variables. Traps the INT09h vector, so that the POST INT09h handler gets
control for IRQ1. Uncompress all available language, BIOS logo, and Silent
logo modules.
13 Early POST initialization of chipset registers.
20 Relocate System Management Interrupt vector for all CPU in the system.
24
Uncompress and initialize any platform specific BIOS modules. GPNV is
initialized at this checkpoint.
2A
Initializes different devices through DIM. See DIM Code Checkpoints section
of document for more information.
2C
Initializes different devices. Detects and initializes the video adapter installed
in the system that have optional ROMs.
2E Initializes all the output devices.
31
Allocate memory for ADM module and uncompress it. Give control to ADM
module for initialization. Initialize language and font modules for ADM. Activate
ADM module.
33 Initializes the silent boot module. Set the window for displaying text information.
37
Displaying sign-on message, CPU information, setup key message, and any
OEM specific information.
38
Initializes different devices through DIM. See DIM Code Checkpoints section
of document for more information. USB controllers are initialized at this point.
39 Initializes DMAC-1 & DMAC-2.
3A Initialize RTC date/time.
3B
Test for total memory installed in the system. Also, Check for DEL or ESC keys
to limit memory test. Display total memory in the system.
3C Mid POST initialization of chipset registers.
40
Detect different devices (Parallel ports, serial ports, and coprocessor in CPU,
… etc.) successfully installed in the system and update the BDA, EBDA…etc.
52
Updates CMOS memory size from memory found in memory test. Allocates
memory for Extended BIOS Data Area from base memory. Programming
the memory hole or any kind of implementation that needs an adjustment in
system RAM size if needed.
60 Initializes NUM-LOCK status and programs the KBD typematic rate.
