μATX BIOS Error Messages
When the μATX board powers on, the BIOS runs power-on self-tests (POST) to
check the board. The BIOS writes error codes to location 80h and tries to write
the codes to the display. If the error is fatal, the POST code indicates the last
successful checkpoint reached. The following table lists the error messages that
are displayed by the BIOS. Another table lists the POST codes displayed by the
BIOS. (S
ee Table 4-12 on page 4-31.)
Once the display is enabled, errors are written to the display as text messages.
These me
ssages are always displayed unless the board is configured for silent
startup or headless operation (no keyboard, mouse, or display).
