Power-On Self Test (POST 2604)
Power-On Self Test (POST)
Each time you power-on the computer, the POST is initiated.
The POST takes up to 15 seconds
to complete, depending on the options installed.
The POST checks the following: system board,
memory, display, keyboard, hard disk drive,
parallel port, and serial port.
To start the POST, power-on the computer. You hear one short beep
when the POST successfully ends.
If the POST cannot be completed successfully, an invalid configuration
error message appears. If F1 is pressed, the system
bypasses the error and attempts to complete POST. Press F1 to
continue or Press F2 to go to Setup.
