The BIOS is a in every computer, that begins a number of diagnostic tests at the start of a computers boot up process. BIOS checks to make sure that different parts and functions of the computer are working, such as, hard drive, the monitor, key board, memory, processor and many others. It configures the PC's hardware so that the operating system can recognize and install the appropriate software device drivers. [3] The BIOS is located in the ROM chip which is on the CMOS chip and all of this is located on the motherboard.
