Beep Codes
Fatal errors that occur during POST are communicated through a series of beeps. All

continue to boot.
If beep codes occur during POST, check the items in the Problem Checklist (at the start
of this chapter), verify that all the hardware is set up properly and securely connected,
and try rebooting. If you still get a beep code, go to the section “If You Need
