Option ROM: BIOS Boot Specification, Overview & Original usage of Option ROMs for booting through expansion cards

An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or sometimes stored along with the main system BIOS), which gets executed to initialize the expansion device and (optionally) add support for the expansion device to the BIOS. In its usual use, it is…
