BIOS Error Beep Codes<br />
During the POST (Power-On Self-Test) routines, which are performed at each<br />
system boot, errors may occur.<br />
Non-fatal errors are those which, in most cases, allow the system to continue to<br />
boot. The error messages normally appear on the screen.<br />
Fatal errors will not allow the system to continue with bootup procedure. If a<br />
fatal error occurs, you should consult with your system manufacturer for possible<br />
repairs.<br />
These fatal errors are usually communicated through a series of audible beeps.<br />
The numbers on the fatal error list correspond to the number of beeps for the<br />
corresponding error.<br />
