Power-On Self-Test (POST)

POST is a series of diagnostic tests that runs automatically when the system is turned on. POST
checks the following items to ensure that the workstation is functioning properly:
Keyboard
Memory modules
Diskette drives
All IDE mass storage devices
Processors
Controllers
If the Power-On Password is set, a key icon appears on the screen while POST is running. You
will need to enter the password before continuing. Refer to Chapter 3, Section 3.1for information
on setting, deleting, or bypassing the password.
If POST finds an error in the system, an audible and/or visual message occurs. For POST error
messages and their solutions refer to
