You need something like this:

option ROM_SIZE=256*1024-64*1024  # This assumes a 64K video BIOS

Use

hexdump | head

or view it in a hex editor.

Note that this needs to be coupled with looking for the signature to make
sure that you're starting in the right place.

Hopefully when you build you'll have a (256-64)*1024 = 192K image that you
can prepend your 64K Video BIOS to.
