10-4 Solving System Problems
Post Error Messages
The NEC Versa computer has a built-in checking program that automatically tests its
components when you turn the system power on. This diagnostic test is called the
Power-On Self-Test (POST). If the system finds a problem during the POST, the
system displays an error message or emits a series of beep signals. If this happens,
follow the instructions in the POST Error Messages table or the Beep Code table, as
appropriate.
If an error message appears before the operating system starts, look up the error
message in the following table. Follow the instructions. If you see other error messages,
the hardware might need repair.
