Basic Input/Output System
(BIOS, ROM BIOS) The part of the {system software} of the {IBM PC} and compatibles that provides the lowest level interface to ref="module.php?name=Lexikon&file=search&eid=1&query=peripheral">peripheral devices and controls the first stage of the ref="module.php?name=Lexikon&file=search&eid=1&query=bootstrap">bootstrap process, including installing the ref="module.php?name=Lexikon&file=search&eid=1&query=operating system">operating system. The BIOS is stored in ref="module.php?name=Lexikon&file=search&eid=1&query=ROM">ROM, or equivalent, in every PC. Its main task is to load and execute the operating system which is usually stored on the computer' s ref="module.php?name=Lexikon&file=search&eid=1&query=hard disk">hard disk, but may be loaded from ref="module.php?name=Lexikon&file=search&eid=1&query=CD-ROM">CD-ROM or ref="module.php?name=Lexikon&file=search&eid=1&query=floppy disk">floppy disk at install time. In order to provide acceptable performance (e.g. for screen display), some software vendors access the routines in the BIOS directly, rather than using the higher level operating system calls. Thus, the BIOS in the compatible computer must be 100% compatible with the IBM BIOS. As if that wasn' t bad enough, many ref="module.php?name=Lexikon&file=search&eid=1&query=application programs">application programs bypass even the BIOS and address the screen hardware directly just as the BIOS does. Consequently, ref="module.php?name=Lexikon&file=search&eid=1&query=register">register level compatibility is required in the compatible' s display electronics, which means that it must provide the same storage locations and identification as the original IBM hardware.
