I must have screwed up the device nodes here, I'm not really sure what happened though. :\ Seems to work now after removing them all and recreating them. This is annoying to do from a fixit floppy, because too many paths are hardcoded into MAKEDEV. :( Anyways I can now boot as well.. >Unfortunately, somehow, the install disk seems to have toasted >the disklabels on both of my disks with very little effort. :( >It did leave the bios partitions intact though. > >Can anyone please tell me how to go about recovering?

I unfortunately do not have real recent backups, or >a way of making them. I seemed to have fixed the damage (after many painful hours...) For anyone interested, this is how I went about it. First, I set a disklabel partition to include all the space in the bios partition. After you do this, you can use dumpfs on the partition to figure out its length. I've found that fsck is a simple way to determine if the partition is/is not part of a ccd, as it majorly complians. :) After I have found one, try the remaining space, etc, until there is none left. This seems fairly simple, if your partitions are actually back to back. Takes a while though..
