Okay, here we go.  Encapsulated in this message is my current disklabel
and config file for the kernel.  The sources are as of 10/25/94, the
binaries are as of 10/20/94 from the central distribution.
I have wd0h labeled as an MS-DOS filesystem, size of my C: partition.
If I type "mount -t msdos /dev/wd0h /mnt", I get the error message:

msdos: mount: Invalid argument.
