Beep Codes - American Megatrends Enterprise-II User Manual

Beep Codes

Errors may occur during POST (Power On
Self Test), which is performed every time
the system is powered on. Fatal errors
(listed below) are usually communicated
through a series of audible beeps. All
errors except Beep Code 8 are fatal. Fatal
errors do not allow the system to
continue.
If POST initializes the system video
monitor, errors can be displayed on the
screen. These errors usually allow the
system to continue. They are listed on
Page 48.
