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 errors. Fatal errors do not allow
the system to continue the boot process. Some errors appear on the
monitor and, in most cases, allow the system to continue the boot
process. They are described on page 36.
