How to Access Motherboard BIOS?

June 15th, 2010

Access BIOS The BIOS is a program pre-installed on computers (with the exception of Macs) that the computer uses to start up. The CPU accesses the BIOS before the operating system is loaded. The BIOS then checks all your hardware connections and locates all of your devices. If everything is OK, the BIOS loads the operating system into the computer’s memory and finishes the boot-up process.

Some of the most common single key commands are:

F1, F2, ESC and DEL.

Each computer and BIOS manufacturer can use a different key or combination of keys in order to enter the System BIOS. Sometimes during system boot when the screen is blank you will see some text in the bottom middle or bottom right of the screen that will tell you what the key sequence is. If not, you may need to consult your computer manual, or contact the manufacturer of your computer to find out what the key or key combination is.
