The Basic Input Output System (BIOS) on the Asus Netbook is the software that allows the operating system of the computer to communicate with the hardware of the machine. If you make changes to the BIOS on your Netbook you can drastically impact the function of your computer as a whole, so use caution when changing any BIOS settings.
Reboot your computer if it is on or power it on if it is off.
As soon as you see the Asus splash screen appear begin tapping the "F2" key until the BIOS menu appears.
Make your required changes to the BIOS, press the "ESC" key, then choose the "Save and Exit" option to save your settings changes and exit the BIOS.
