VBiosFinder: extract a VBIOS from a BIOS update.
This tool attempts to extract a VBIOS from a bios update.
Dependencies include: UEFIDump and rom-parser.
UEFIDump, of course, is included with UEFITool. But rom-parser is new to me.
To view ROM contents:
usage: rom-parser [ROM file]
This program does not have support for reading the ROM from pci-sysfs, please do this manually in advance, ex:
echo 1 > rom
cat rom > /tmp/image.rom
echo 0 > rom
Pass the resulting image file as the argument to this program.
To modify ROM conents:
usage: rom-fixer [ROM file]
Obtain ROM as above, program prompts for modifying ROM vendor and device IDs and invalid checksums.
IMPORTANT: rom-fixer will update the ROM file in place. Make a backup!
