Subject:   HD error with disklabel

I get a weird error using disklabel.
"Warning, partition c doesn't start at 0!
Warning, partition c doesn't cover the whole unit!
Warning, An incorrect partition c may cause problems for standard
system"

The thing is, it occured after a double upgrade:
FreeBSD 4.6.2 -> 5.0
BIOS upgrade (better support for large disks).

The weird part is that my old 4.6.2 disk is still in, which never gave
those
errors before, well it now does too.

The system is FreeBSD 5.0 on a Digital PC 3500.

Thanks for any suggestions.
