| BIOS The
BIOS is what's coded into a PC's ROM to provide the basic instructions for
controlling system hardware. The operating system and application programs
both directly access BIOS routines to provide better compatibility for
such functions as screen display. Some makers of add-in boards such as
graphics accelerator cards provide their own BIOS modules that work in
conjunction with (or replace) the BIOS on the system's motherboard. |
