Digidoc 80-Port POST Error Code List
POST (hex) Description
CF Test CMOS R/W functionality.
C0
Early chipset initialization:
-Disable shadow RAM
-Disable L2 cache (socket 7 or below)
-Program basic chipset registers.
C1
Detect memory:
-Auto-detection of DRAM size, type and ECC.
-Auto-detection of L2 cache (socket 7 or below)
C3
Expand compressed BIOS code to DRAM.
C5
Call chipset hook to copy BIOS back to E000 & F000 shadow RAM.
01
Expand the Xgroup codes locating in physical address 1000:0
03 Initial Superio_Early_Init switch.
05
Blank out screen.
Clear CMOS error flag.
07
