Appendix B

BIOS POST Checkpoint Codes

When AMIBIOS performs the Power On Self Test, it writes checkpoint codes to I/O port 0080h. If the computer cannot complete the boot process, diagnostic equipment can be attached to the computer to read I/O port 0080h.

B-1 Uncompressed Initialization Codes

The uncompressed initialization checkpoint codes are listed in order of execution:

Checkpoint

D0h

D1h

D3h

D4h

D5h

Code Description

The NMI is disabled. Power on delay is starting. Next, the initialization code check- sum will be verifi ed.

Initializing the DMA controller, performing the keyboard controller BAT test, starting memory refresh and entering 4 GB fl at mode next.

Starting memory sizing next.

Returning to real mode. Executing any OEM patches and setting the Stack next.

Passing control to the uncompressed code in shadow RAM at E000:0000h. The initialization code is copied to segment 0 and control will be transferred to segment 0.
