BIOS
by rob

BIOS, your computer's Basic Input/Output System, is a set of programs stored in non-volatile memory on the motherboard of the computer. Programs in non-volatile memory are retained even with the power off but can be re-written using a special "Flash" utility. The BIOS programs control the computer system when it is first powered on, testing, detecting, and configuring the hardware. The BIOS loads and then turns control over to the disk-based Operating System and continues to provide limited hardware functions after the OS loads. To support newer, faster hardware and components that may have been shipped after the system board was designed, the BIOS needs to be changed or updated with the new information.

Warning! Never interrupt a BIOS flash while it is running; installing the wrong version or interrupting the flash process can make the system unusable.
