Audible and visual messages occur before the operating system starts if the POST encounters a
problem. POST checks the following items to ensure that the computer system is functioning properly:
● Keyboard
DIMMs
●
Diskette drives
●
All mass storage devices
●
CPUs
●
Controllers
●
Fans
●
Temperature sensors
●
Cables (front/rear panels, audio, and USB ports)
●
The table shown next describes the POST error messages.
