The principal job of a computer’s BIOS is to govern the early stages of the startup process, ensuring that the operating system is correctly loaded into memory. BIOS is vital to the operation of most modern computers, and knowing some facts about it could help you troubleshoot issues with your machine.
What is the most important role of BIOS?
BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.
Can a computer run without BIOS?
If by “computer” you mean IBM compatible PC, then no, you must have the BIOS. Any of the common OS’s today have the equivalent of “the BIOS”, i.e., they have some embedded code in a non-volatile memory that has to run to boot the OS. It’s not just IBM compatible PC’s.
