BIOS Error Beep Codes

This section lists POST (Power On Self Test) error beep codes for the Phoenix BIOS. POST error beep codes are divided into two categories: recoverable and terminal. This section lists Beep Codes for recoverable POST errors.

1 long and two short beeps - video conﬁ guration error 1 repetitive long beep - no memory detected

1 continuous beep (with front panel OH LED on) - system overheat
