BIOS Chip

Aside from the processor, the most important chip on the motherboard is the Basic Input/Output System (BIOS) chip.

This special memory chip contains the BIOS software that tells the processor how to interact with the rest of the hardware in the computer.

The BIOS chip is easily identified: If you have a non-clone computer (Compaq, IBM, HP, and so on), this chip has on it the name of the manufacturer and usually the word BIOS.

For example, the BIOS chip for a Compaq has something like Compaq BIOS printed on it. For clones, the chip usually has a sticker or printing on it from one of the major BIOS manufacturers (AMI, Phoenix/Award, Winbond, and so on).
