POST Routine Description

 

 

12h

Use walking 1’s algorithm to check out interface in CMOS circuitry. Also set real-

 

time clock power status, and then check for override.

 

 

13h

Reserved

 

 

14h

Program chipset default values into chipset. Chipset default values are

 

MODBINable by OEM customers.

 

 

15h

Reserved

 

 

16h

Initial onboard clock generator if Early_Init_Onboard_Generator is defined. See

 

also POST 26h.

 

 

17h

Reserved

 

 

18h

Detect CPU information including brand, SMI type (Cyrix or Intel) and CPU level

 

(586 or 686).

 

 

19h

Reserved

 

 

1Ah

Reserved

 

 

1Bh

Initial interrupts vector table. If no special specified, all H/W interrupts are directed

 

to SPURIOUS_INT_HDLR & S/W interrupts to SPURIOUS_soft_HDLR.

 

 

1Ch

Reserved

 

 

1Dh

Initial EARLY_PM_INIT switch.

 

 

1Eh

Reserved

 

 

1Fh

Load keyboard matrix (notebook platform)

 

 

20h

Reserved

 

 

21h

HPM initialization (notebook platform)

 

 

22h

Reserved

 

 

23h

1 Check validity of RTC value: e.g. a value of 5Ah is an invalid value for RTC

 

minute.

 

2 Load CMOS settings into BIOS stack. If CMOS checksum fails, use default value

 

instead.

 

 

24h

Prepare BIOS resource map for PCI & PnP use. If ESCD is valid, take into

 

consideration of the ESCD’s legacy information.

 

 

25h

Early PCI Initialization:

 

Enumerate PCI bus number

 

Assign memory & I/O resource

 

Search for a valid VGA device & VGA BIOS, and put it into C000:0

 

 

26h

1 If Early_Init_Onboard_Generator is not defined Onboard clock generator

 

initialization. Disable respective clock resource to empty PCI & DIMM slots.

 

2 Init onboard PWM

 

3 Init onboard H/W monitor devices

 

 

27h

Initialize INT 09 buffer

 

 

28h

Reserved

 

 

29h

1 Program CPU internal MTRR (P6 & PII) for 0-640K memory address.

 

2 Initialize the APIC for Pentium class CPU.

 

3 Program early chipset according to CMOS setup. Example: onboard IDE

 

controller. Measure CPU speed.

 

 

2Ah

Reserved

 

 

2Bh

Invoke Video BIOS

 

 

2Ch
