How to Get to BIOS Screens in Asus Eee PC 1201 HAs
The computer basic input/output system (BIOS) is responsible for the boot process on your computer. It tells the computer which devices to boot up and what order to boot them in. It also contains other information about your computer and runs tests when your system boots up to ensure that all hardware is working properly. You may need to access your BIOS to change a setting; this is done just before your Asus Eee PC 1201 HAs boots into the operating system.
Turn on or restart your computer.
Press "F2" to display the POST screen. This is the first screen you see when you turn the computer on; it shows lists of technical data, in white, against a black background.
Press "F2" again to access the BIOS.
Make any necessary changes. Press "F10" to save your new settings and exit.
