INT 1A - PCI BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. v2.0c+ - READ CONFIGURATION DWORDDoubleword; four bytes. Commonly used to hold a 32-bit segment:offset or selector:offset address. (Intel devices) {#idx37658}
