Accessing BIOS

To access the BIOS setup menu, hold the F1 key down while the PC is powering
up. This takes you to the BIOS setup menu. If you go to the BIOS setup menu by
accident, simply select the menu item Exit without saving.

Monitoring the power-on self-test (POST)

Your computer performs the power-on self-test everytime the PC is turned on.
POST tests the memory of the PC and reports the total memory installed. It also
checks the processor type and speed, the hard disk type, and the CD-ROM type.
Normally, POST runs in the background and you do not see the results. To
display the POST for results, press the tab key when the PC begins to power up.
Be aware that POST runs very quickly and the PC will automatically begin the
startup process when POST is complete.
