Greetings! I have a few older (read: ancient!) Compaq systems I'd like to put FBSD on. Unfortunately, Compaq (in their infinite wisdom -- NOT!) have fixed disk parameter tables in their BIOS. So, regardless of the size of the (IDE) disk I might install, I am limited to whatever geometry Compaq has chosen to support. I'd like to cut a new set of EPROMs with an altered disk table but the POST screams about bad checksums. Anyone have a clue as to the algorithm employed and the location of the checksum image (before I start disassembling code)? Thx, --don
