POST Error Codes and Messages

Whenever a recoverable error occurs during POST, BIOS displays a message on the
video display screen and causes the speaker to beep as the message appears. BIOS also
issues a beep code (one long tone followed by two short tones) during POST if the
video configuration fails or if an external ROM module does not a checksum of zero.
The "POST Error Codes and Messages" table is a list of the possible error codes and
messages written at the start of each POST test. The "POST Error Beep Codes" table is
a list of beep codes issued for each POST test. Figure 5-1 shows the location of specific
components referenced in the POST Error Codes and Messages Table.
