Fatal errors that occur during POST are communicated through a series of beeps. All beep
code errors, except beep code 8, are fatal errors and do not allow the system to 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 Assistance" at the
end of this chapter.
Beep Codes are listed in the table that follows.
