BIOS POST Codes
A.1 BIOS POST Codes
The AMI BIOS supplies additional checkpoint codes, which are documented online at
https://
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 AOM-SPI80-V).
For information on AMI updates, please refer to https://www.ami.com/products/.
