There are various
methods for entering the BIOS or CMOS setup
depending on the make, model and age of your computer. I will try and explain
some of the most popular methods.
Most modern computers
will require you to press one of the following keys during start up:
§ F1
§ F2
§ DEL
§ ESC
§ F10
You should press the key when you see a
message such as press <f2> to enter BIOS or try tapping
the appropriate key slowly during startup.
On some modern computers, pressing and holding
down a key during boot will cause a stuck key error. This may give you the
option to enter BIOS setup
Older computers may require one of the
following key sequences during startup:
§ CTRL + ALT + ESC
§ CTRL + ALT + INS
§ CTRL + ALT + ENTER
§ CTRL + ALT + S
§ PAGE UP KEY
§ PAGE DOWN KEY
