I have followed the procedure of booting up on the kernel floppy, and
performing "copy_kernel", doing halt, and then hitting a key to restart.
No luck. I tried renaming netbsd to netbsd.bak (in case netbsd was on top
of a bad disk sector), and doing "kernel_copy" again, halting and restarting,
but no luck. I tried copying the kernel to netbsd.old from the floppy as
well, but receive the same error "invalid format". Not sure if it would be
much help to get a new kernel disk since I can boot off it on a floppy fine....
For the information, I'm using a WDC31000 1 Giga disk (2100 cylinders, 16
headers, 63 sectors/track). I've got msdos on Cyl 0-1021, and BSD on 1023
to 2098. I left a few cylinders free since the *BSD FAQ mentioned that
disklabel needs some space or it trashes the MS-DOS stuff (and it's too much
effort to actually try to test these statements :-).

Thanks! I can now mount the msdos partition fine!
