Port 80h POST Codes

During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O
port 80h. If the POST fails, execution stops and the last POST code generated is left
at port 80h. This code is useful for determining the point where an error occurred.
The following tables provide information about the POST codes generated by the BIOS:
Table 33 lists the Port 80h POST code ranges
•
Table 34 lists the Port 80h POST codes themselves
•
Table 35 lists the Port 80h POST sequence
•
NOTE
In the tables listed above, all POST codes and range values are listed in hexadecimal.

Explanation
The battery may be losing power. Replace the battery soon.
The CMOS checksum is incorrect. CMOS memory may have been
corrupted. Run Setup to reset values.
Memory size has decreased since the last boot. If no memory
was removed, then memory may be bad.
System did not find a device to boot.
Subsystem
Entering SX states S0 to S5.
Resuming from SX states. 0x10 –0x20 – S2, 0x30 – S3, etc.
Security (SEC) phase
PEI phase pre MRC execution
MRC memory detection
PEI phase post MRC execution
Recovery
Platform DXE driver
CPU Initialization (PEI, DXE, SMM)
I/O buses: PCI, USB, ATA, etc. 0x5F is an unrecoverable error. Start
with PCI.
BDS
Output devices: All output consoles.
For future use
Input devices: Keyboard/Mouse.
