Uh, well, the dump was done a long time ago by great hierophant, but he trimmed the 27256 rom dump from 32kb to 24kb, and I *still* don't know what the chunk he cut off contained, but it isn't used by the card.

Yeah, that whole site is great. That page in particular finally explains the "fd0 is a post-1991 82077" message that the kernel shows on boot.
