Computer Maintenance - BIOS
Lab 1: Getting into the BIOS
Information retrieved from “howstuffworks.com”
Student Name: _____________________________
Date: __________
To enter the CMOS Setup, you must press a certain key, or combination of keys, during
the initial startup sequence. Most systems use "Esc," "Del," "F1," "F2," "Ctrl-Esc," or
"Ctrl-Alt-Esc" to enter the setup. There is usually a line of text at the bottom of the
display that tells you to "Press ___ to Enter Setup."
Once you have entered the setup, you will see a set of text screens with a number of
options. Some of these are standard, while others vary according to the BIOS
manufacturer. Common options include:
•
•
•
•
•
•
•
•
•
System Time/Date – Set the system time and date.
Boot Sequence – The order in which the BIOS will try to load the operating
system
Plug and Play – A standard for auto-detecting connected devices; it should be
set to "Yes" if your computer and operating system both support it.
Mouse/Keyboard – "Enable Num Lock," "Enable the Keyboard," "Auto-Detect
Mouse"...
Drive Configuration – Configure hard drives, CD-ROM, and floppy drives.
Memory – Direct the BIOS to shadow to a specific memory address.
Security – Set a password for accessing the computer.
Power Management – Select whether to use power management, as well as the
amount of time for standby and suspend.
Exit – Save your changes, discard your changes, or restore the default settings.
CMOS Setup
Be very careful when making changes to the setup. Incorrect settings may keep your
computer from booting. When you are finished with your changes, you should choose
"Save Changes" and exit. The BIOS will then restart your computer so that the new
settings can take effect.
