POST Checkpoint Codes
When AMIBIOS performs the Power On Self Test, it writes diagnostic
codes (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. The following AMIBIOS POST
checkpoint codes are valid for all AMIBIOS products with a core BIOS
date of 7/15/95 (Enhanced).
