it is trivial to grab bios image. you just run 'dd' under linuxbios while 
booted from pcbios. In that way you don't have to wonder what they used to 
pack/compress the bios image.

what is tricky is that the vga bios usually expect to run in 16 bit mode 
and with some of pc bios routines available. There's Ollie's testvga, 
there's ADLO which both attemp to solve this issue.
