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."
07
Fixes CPU POST interface calling pointer.
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 Start -- Disable Cache – Init Local 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 Init Exit
0A
Initializes the 8042 compatible Key Board Controller
0B
Detects the presence 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 INT09h 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. GPNV is initialized at this
checkpoint.
30
Initialize System Management Interrupt.
2A
Initializes different devices through DIM.
See DIM Code Checkpoints section of document for more information.
2C
nitializes 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
