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.
