bios_extract is a GPL tool for extracting individual modules from proprietary BIOS/UEFI images.
This utility should work on most modern UNIX-like operating systems; it has been tested on at least Linux and FreeBSD. It is very useful for extracting PCI Expansion ROMs from onboard devices, like IGP graphics, raid controllers, nic boot roms, etc, for inclusion in a coreboot image.
