POST Checkpoint Codes

When AMIBIOS performs the Power On Self Test, it writes diagnostic codes checkpoint codes to I/O port 0080h where the POST code display is connected.

Table D-4 Uncompressed Initialization Codes

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

Checkpoint

Description

Code

 

D0h

The NMI is disabled. Power on delay is starting. Next,

the initialization code checksum will be verified.

 

 

Initializing the DMA controller, performing the

D1h

keyboard controller BAT test, starting memory refresh,

 

and entering 4 GB flat mode next.

D3h

Starting memory sizing next.

D4h

Returning to real mode. Executing any OEM patches

and setting the stack next.

 

 

Passing control to the uncompressed code in shadow

D5h

RAM at E000:0000h.The initialization code is copied to

 

segment 0 and control will be transferred to segment 0.

 

Control is in segment 0. Next, checking if <Ctrl>

 

<Home> was pressed and verifying the system BIOS

 

checksum.

D6h

If either <Ctrl> <Home> was pressed or the system

 

BIOS checksum is bad, next will go to checkpoint code

 

E0h.

 

Otherwise, going to checkpoint code D7h.

D7h

Main BIOS runtime code is to be decompressed and

control to be passed to main BIOS in shadow RAM.
