Can anyone point me to some info on mounting DOS extended
partitions...I've gone through what I could find at netbsd.org and am
still having some trouble figuring out what's going on with drive
geometry. I haven't been able to figure out how to specify the size of
the partitions to disklabel.
what disklabel tells me (7944 cyl, 1008 sectors/cyl) differs from the
992/128 geometry I know about.
machine is working...should I worry about changing disklabel for my
NetBSD partitions?
Thanks for any help...(info follows)
