Post Check Points

Checkpoint	Description

03	Disable NMI, Parity, video for EGA, and DMA controllers. Initialize BIOS, POST, Runtime
	data area. Also initialize BIOS modules on POST entry and GPNV area. Initialized 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."

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 ?C 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.
