I don't recall ever having a problem starting a DOS partition on cylinder
0, but I'm running on a 286 system.  I wouldn't think it would make a
difference, though, since DOS is DOS is DOS ...  However, to overcome
your immediate problem, when you install UNIX, you can allocate a DOS
partition 2 cylinders larger than you need, then go back with fdisk to
delete the DOS partition, and re-create it with the correct size starting
at cylinder 2.  I would think this would keep anything from scribbling
on the first two cylinders.
