Description

 

 

 

 

 

 

1Dh

Initial EARLY_PM_INIT switch.

 

 

1Fh

Load keyboard matrix (notebook platform)

 

 

21h

HPM initialization (notebook platform)

 

 

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.

 

 

 

 

3.

Prepare BIOS resource map for PCI & PnP use. If ESCD is

 

 

 

valid, take into consideration of the ESCD¡¦s legacy information.

 

 

4.

Onboard clock generator initialization.

Disable respective clock

 

 

resource to empty PCI & DIMM slots.

 

 

 

 

5.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.

 

 

 

25h

PCI Bus Initialization

 

 

 

26h

Init clock Generator

 

 

 

27h

Initialize INT 09 buffer

 

 

 

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.

 

 

 

 

4. Measure CPU speed

 

 

 

2Bh

Invoke video BIOS.

 

 

 

2Dh

1.

Initialize multi-language

 

 

 

 

2.

Put information on screen display, including Award title, CPU type,

 

 

CPU speed

 

 

 

33h

Reset keyboard except Winbond 977 series Super I/O chips.

 

3Ch

Test 8254

 

 

 

3Eh

Test 8259 interrupt mask bits for channel 1.

 

40h

Test 8259 interrupt mask bits for channel 2.

 

43h

Test 8259 functionality.

 

 

 

47h

Initialize EISA slot

 

 

 

49h

1. Calculate total memory by testing the last double word of each 64K page.

 

 

2.

Program write allocation for AMD K5 CPU 64K page.

 

4Eh

1. Program MTRR of M1 CPU

 

 

 

 

2.

Initialize L2 cache for P6 class CPU & program CPU with proper

 

 

cacheable range.

 

 

 

 

3.

Initialize the APIC for P6 class CPU.

 

 

 

 

4.

On MP platform, adjust the cacheable range to smaller one in case the

 

 

cacheable ranges between each CPU are not identical.
