Post Errors - American Megatrends EZ-Flex User Manual

POST Errors

Errors can occur during POST (Power On Self Test),
performed every time the system is powered on.
Fatal errors (see 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.
Displayed errors usually allow the system to continue the
boot process. They are described beginning on page 52.
