When the system is powered on, the BIOS will initiate the Power-On-Self-Test (POST) routines. These
routines perform various diagnostic checks. If an error is encountered, the error will be reported in one of
two different ways:

If the error occurs before the display device is initialized, a series of beeps will be transmitted.

If the error occurs after the display device is initialized, the screen will display the error message.
Powering on the computer and immediately pressing <Del> allows you to enter Setup. Another way to enter
Setup is to power on the computer and wait for the following message during the POST:
