In Case of Problems
If you discover that you have trouble booting the computer after making and saving the changes
with the BIOS setup program, you can restart the computer by holding the power button down until
the computer shuts off (usually within 4 seconds); resetting by pressing CTRL-ALT -DEL; or
clearing the CMOS.
The best advice is to only alter settings that you thoroughly understand. In particular, do not
change settings in the Chipset section unless you are absolutely sure of the outcome. Tyan or
your system manufacturer for the best performance and reliability carefully chose the Chipset
defaults. Even a seemingly small change to the Chipset setup options may cause the system to
become unstable or unusable.
Setup Variations
Not all systems will have the same BIOS setup layout or options. While the basic look and function
of the BIOS setup remains more or less the same for most systems, the appearance of your Setup
screen may differ from the charts shown in this section. Each system design and chipset
combination requires a custom configuration. In addition, the final appearance of the Setup
program depends on the system designer. Your system designer may decide that certain items
should not be available for user configuration, and remove them from the BIOS setup program.
NOTE: On the following pages, options written in bold type represent the BIOS Setup default.
