Beep Codes
Fatal errors, listed below, are communicated through a series of audible beeps. All errors except Beep Code 8 are fatal. Fatal
errors do not allow the system to continue the boot process. Consult the component manufacturer for possible repairs if a fatal
error occurs.
If AMIBIOS can initialize the system video display, it displays error messages. Often, these messages (listed on page ) are not
as serious as beep codes and allow the system to continue the boot process.
