Perhaps, BIOS resides at this address. Try addressed in range 0xC0000-0xEFFFF.
You can just try every address in this range with 8K step but better
read the description of your machine, look in setup and find 8K of
free space in this range.

BTW, do you have the latest version with patches from Oleg Panaschenko ?
If not I can send it to you, it has some serious bugs fixed.
