A.1 BIOS POST Codes
The AMI BIOS supplies checkpoint codes, which are documented online at http://www.
supermicro.com/support/manuals/ ("AMI BIOS POST Codes User's Guide").
When BIOS performs the Power On Self Test, it writes checkpoint codes to I/O port 0080h.
If the computer cannot complete the boot process, a diagnostic card can be attached to the
computer to read I/O port 0080h (Supermicro p/n AOC-LPC80-20).
