What do I have to do in order to see the dos part of my disk?

I have netbsd/i386 1.0, a 486 PC, an adaptec 1542C scsi controller with one
single 1 gb disk drive which has its lowest 100 mb reserved for DOS,
while netbsd resides on the upper 900 mb. I have set it up so that I
can boot from either netbsd or dos.

Under netbsd, I can mount the floppies by mtools or by mount_msdos, however,
it would be nice to be able to see the dos part of the hard drive under netbsd.

Any comments are welcome.
