If you have set a power-on password, a password prompt appears. You must enter your password in order for the first screen of your operating system or application program to appear.

(Note that the screen will sometimes display multiple error codes and descriptions.) For more information about what caused an error message to appear and what action to take, refer to "Solving POST Error Message Problems" on page 68 and "POST Message Charts" on page 71.
