BIOS (Basic Input and Output System) records hardware
parameters of the system in the CMOS
on the motherboard. Its major functions include
conducting the Power-On Self-Test (POST) during
system startup, saving system parameters and loading operating system,
etc. BIOS includes a BIOS Setup program that allows the user to modify
basic system configuration settings or to activate
certain system features.
When the power is turned off, the battery on the motherboard supplies the necessary power
to the CMOS to keep the configuration values in the
CMOS.
To access the BIOS Setup program, press the
<Delete> key during the POST when the power
is turned on.
To upgrade the BIOS, use either the GIGABYTE
Q-Flash or @BIOS utility.
• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without
entering the operating system.
• @BIOS is a Windows-based utility that
searches and downloads the latest version of
BIOS from the Internet and updates the BIOS.
• Because BIOS flashing is potentially risky, if
you do not encounter problems using the
current version of BIOS, it is
recommended that you not flash the BIOS.
To flash the BIOS, do it with caution.
Inadequate BIOS flashing may result in system malfunction.
• It is recommended that you not alter the
default settings (unless you need to) to prevent
system instability or other unexpected results. Inadequately altering the
settings may result in system's failure to boot. If this occurs, try to clear the CMOS
values and reset the board to default values.
(Refer to the "Load Optimized Defaults" section in
this chapter or introductions of the
battery/clear CMOS jumper in Chapter 1 for
how to clear the CMOS values.)
