With the BIOS correctly configured, your PC is a silver machine that zips you along
the information superhighway or conjures up hordes of detailed and vicious mutants
for you to annihilate. And with the BIOS incorrectly configured, your PC may be a
mess??”unstable, balky, and with key components not functioning as they should.

Project 6: Learn to Work with Your PC??™s BIOS 55
If your PC is working correctly, you should make BIOS changes only with caution
and only when necessary. Before making a change, write down the current settings so
that you can restore them if the changes have any unfortunate effects.
If you??™ve made a change to the BIOS that seems to have caused trouble, and you??™ve lost your
notes about how the settings were beforehand, you may need to load the BIOS??™s default settings
to recover. These settings may not be exactly what you had before you made changes, but they
should provide a stable and functional configuration. To load the default settings, look for an
option such as Setup Defaults or Load Setup Defaults in the BIOS, and then execute it.
Step 2: Reach Your PC??™s BIOS
To reach your PC??™s BIOS, you typically have to press a designated key during startup.
Which key that is depends on the BIOS, but many BIOSes use one of these keys:
DELETE
F2
F10
?—? ?—? ?—?
ESC
ALT, F1
ESC, F1
?—? ?—? ?—?
To find out which key to use, boot your PC and watch the messages that appear
on the screen.
