4.11 BIOS POST Check Point List
AMIBIOS provides all IBM standard Power On Self Test (POST) routines as
well as enhanced AMIBIOS POST routines. The POST routines support CPU
internal diagnostics. The POST checkpoint codes are accessible via the
Manufacturing Test Port (I/O port 80h).
Whenever a recoverable error occurs during the POST, the system BIOS will
display an error message describing the message and explaining the problem in
detail so that the problem can be corrected.
During the POST, the BIOS signals a checkpoint by issuing one code to I/O
address 80H. This code can be used to establish how far the BIOS has executed
through the power-on sequence and what test is currently being performed. This
is done to help troubleshoot faulty system board.
If the BIOS detects a terminal error condition, it will halt the POST process and
attempt to display the checkpoint code written to port 80H. If the system hangs
before the BIOS detects the terminal error, the value at port 80H will be the last
test performed. In this case, the terminal error cannot be displayed on the screen.
The following POST checkpoint codes are valid for all AMIBIOS products with a
core BIOS date of 07/15/95 version 6.27 (Enhanced).
