POST Code Checkpoints
The POST checkpoints are the largest set of checkpoints during the BIOS pre-boot process. The following
table describes the type of checkpoints that may occur during the POST portion of the BIOS:
Checkpoint Description
03 Disable NIMI,Parity, video for EGA, and DMA controllers. Initialize BIOS, POST,
and Runtime data area. Also initialize BIOS modules on POST entry and GPNV
area. Initialize CMOS as mentioned in the Kernel Variable “wCMOSFlags”.
04 Check CMOS diagnostic byte to determine if battery power is OK and CMOS
checksum is OK. Verify CMOS checksum manually by reading storage area.
If the CMOS checksum is bad, update CMOS with power-on default values and
clear passwords. Initialize status register A.
Initializes data variables that are based on CMOS setup questions.
Initializes both the 8259 compatible PICs in the system.
05 Initializes the interrupt controlling hardware (generally PIC) and interrupt vector
table.
06 Do R/W test to CH-2 count reg. Initialize CH-0 as system timer. Install the
POSTINT1Ch handler. Enable IRQ-0 in PIC for system timer interrupt.
Traps INT1Ch vector to “POSTINT1ChHandlerBlock”.
08 Initializes the CPU. The BAT test is being done on KBC.
Program the keyboard controller command byte is being done after Auto
detection of KB/MS using AMI KB-5.
C0 Early CPU Init Star--Disable Cache -- Init Loal APIC
C1 Set up boot strap processor Information
C2 Set up boot strap processor for POST
C5 Enumerate and set up application processors
C6 Re-enable cache for boot strap processor
C7 Early CPU lnit Exit
0A Initializes the 8042 compatible Keyboard Controller
0B Detects the processor of PS/2 mouse
0C Detects the presence of Keyboard in KBC port
0E Testing and initialization of different input devices. Also, update the Kernel
Variables.
Traps the INT09h vector, so that the POST INT9h handler gets control for
IRQ1. Uncompress all available language, BIOS logo, and Silent logo modules.
13 Early POST initialization of chipset registers
24 Uncompress and initialize any platform specific BIOS modules
30 Initialize System Management Interrupt
2A Initializes different devices through DIM.
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 moudle.
33 Initializes the silent boot module. Set the window for displaying text information.
