Award BIOS Setup
4.1 Introduction
This chapter discusses the Setup program built into the BIOS. The
Setup program allows users to configure the system. This configuration
is then stored in battery-backed CMOS RAM so that it retains the Setup
information while the power is off.
4.2 Starting Setup
The BIOS is immediately active when you turn on the computer. While
the BIOS is in control, the Setup program can be activated in one of two
ways:
1. By pressing <Del> immediately after switching the system on, or
2. By pressing the <Del> key when the following message appears
briefly at the bottom of the screen during the POST (Power On Self-
Test).
Press DEL to enter SETUP.
If the message disappears before you respond and you still wish to enter
Setup, restart the system to try again by turning it OFF then ON or
pressing the "RESET" button on the system case. You may also restart
by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do
not press the keys at the correct time and the system does not boot, an
error message will be displayed and you will again be asked to...
PRESS F1 TO CONTINUE, DEL TO ENTER SETUP
