Thanks for your reply. I have a few questions:

I don't think there is a problem with the BIOS. BIOS translation only
happens with >1024 cyls, the BIOS thinks there are 1024. In any case
the BIOS is only involved while booting, and both FreeBSD 1.1 and 2.0
boot successfully, and 1.1 can read the DOS filesystem.
wd0 has a FreeBSD 1.1 disklabel. Perhaps this could be the problem.
Are the 1.1 and 2.0 disklabels compatible? I have resisted relabelling
wd0 as I want to be able to continue to use 1.1 until I am happy that
2.0 is solid on my system.
