- BIOS_interrupt_call abstract "BIOS interrupt calls are a facility that DOS programs and some other software, such as boot loaders, use to invoke the facilities of the Basic Input/Output System on IBM PC compatible computers. Some operating systems also use the BIOS to probe and initialize hardware resources during their early stages of booting.In all computers, software instructions control the physical hardware (screen, disk, keyboard, etc.) from the moment the power switch is pressed.The BIOS, preloaded in the mainboard, takes control as the machine is turned on, initializes the hardware, loads and runs the OS loader, and provides basic hardware control to the operating system installed on the machine.Operating systems communicate with the BIOS software, in order to control the installed hardware. This system of communication is called an interrupt.The basic idea is, BIOS and the operating system share an agreed-upon area of the computer's memory, to pass messages. The messages are broken into categories, each with its own "interrupt number", and contains sub-categories ("function numbers"). In practice, the operating system software "calls" to BIOS software by specifying an interrupt and function number, followed with whatever data needs to go in or out of the attached hardware.The BIOS software "responds" with an error code if not successful, or with whatever data was requested if successful. The data itself can be as small as one bit or as large as an entire raw disk sector, being read or written (thousands of bytes).Many modern operating systems (such as newer versions of Windows and Linux) bypass the built-in BIOS interrupt communication system altogether, preferring to use their own software to control the attached hardware directly.".
