What I want to do is 1) dos format the dos partition. Something must be
screwed up in the MBR because the partition is not available. If I boot
up a floppy it prints invalid media type reading drive C. If I run fdisk
on the floppy it prints garbage and hangs.
2) I want to mount the partition in Freebsd.
Mount fails, says wrong superblock, fsck says magic number wrong
can't read disklabel.
I'm not worried about losing anything in the dos partition, but I don't
want to damage the freebsd partition.
Is there a program around that can be run from a dos floppy to fix the
MBR?
