BIOS Setup
The SQ575 mainboard uses an Award BIOS, which is stored in a Flash EEPROM and which
can be upgraded using a floppy disk-based program. The BIOS has a built-in Setup program
that allows users to modify the basic system configuration setting. The settings are then stored
in a dedicated battery-backed memory, called CMOS RAM, that retains the information when
the power is turned off. The BIOS provides critical low-level support for the system central
processing, memory, and I/O subsystems. The Award BIOS has been customized by adding
important, but nonstandard, features such as virus and password protection, power
management, and detailed fine-tuning of the chipset controlling the system. The rest of this
manual is intended to guide you through the process of configuring your system using Setup.
4.1
Starting Setup
The Award BIOS is immediately activated when you first turn on the computer. The BIOS
reads system configuration information in CMOS RAM and begins the process of checking
out the system and configuring it through the power-on self test (POST). When these
preliminaries are finished, the BIOS seeks an operating system on one of the data storage
devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands
control of system operations to it.
To start Setup, press the <Del> key some time before or while a message similar to this
appears briefly at the bottom of the screen during POST:
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you respond and you still wish to enter Setup, reboot the
system to try again by turning the system 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 reboot, an error
message will be displayed at the bottom of the screen and you will again be asked to,
Press F1 to continue, DEL to enter SETUP
