A-2 Additional BIOS POST Codes
The aMI BIOs supplies additional checkpoint codes, which are documented online at
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).
