I downloaded and installed bios_extract via:

git clone http://review.coreboot.org/p/bios_extract.git
cd bios_extract
make

I tried to run bios_extract against both of my rom files (which I've read from both chips) but get the same error message:

./bios_extract ../MyROMs/original/x230-4GB.rom
and
./bios_extract ../MyROMs/original/x230-8GB.rom

in both cases I get the result:

"Error: Unable to detect BIOS Image type"

I have verified those files by reflashing them after flashing coreboot and as everything was working both files are ok.

Do I need to combine them into one big file or why can't I use bios-extract to get the VGA ROM out of it?
