Everything about Option ROM
Firmware to add BIOS support for a device
An option ROM for the PC platform is a piece of firmware that resides in ROM on an expansion card, 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 essentially a driver that interfaces between the BIOS API and expansion hardware. Technically, an option ROM is firmware that is executed by the BIOS after POST and before the BIOS boot process, gaining complete control of the system and being generally unrestricted in what it can do. The BIOS relies on each option ROM to return control to the BIOS so that it can either call the next option ROM or commence the boot process. For this reason, it is possible for an option ROM to keep control and preempt the BIOS boot process. The BIOS generally scans for and initializes option ROMs in ascending address order at 2 KB address intervals within two different address ranges above address C0000h in the conventional (20-bit) memory address space; later systems may also scan additional address ranges in the 24-bit or 32-bit extended address space.
