The BIOS is the fixed program ( usually in FLASH memory ) that starts up the computer.
Each BIOS has its own way of getting into its Setup program – this is part of the BIOS that allows you to change how the computer starts up.
It often has a blue background, and uses the arrow keys, PageUp, PageDown and Enter keys to change the settings.
Once you have “got into” or “accessed” the BIOS, you can change the boot order settings so that the floppy disk is checked first to see if it contains a bootable program.
There is usually a message telling you how to enter the BIOS setup program as the computer starts up, such as “Press F2 for Setup” .
Some computers ( e.g. HP, Dell, Gateway ) display a company logo which hides this message. Press the Esc or Tab key to remove it when it appears.
