Solving System Problems
POST Error Messages
The NEC Versa VXi 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 POST, the system
displays an error message. If this happens, follow the instructions in the POST error
message table.
