BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
How does an operating system work with BIOS?
are available and loading the operating system (OS) into main memory. After start-up, the BIOS program manages data flow between the OS and the peripherals, so neither the OS nor the application programs need to know the details of the peripherals (such as hardware addresses).
What is the main function of BIOS?
The BIOS’s primary function is to handle the system setup process including driver loading and operating system booting. The CMOS’s primary function is to handle and store the BIOS configuration settings.
