Above is my mountlist for the 296N, I've had no serious problems with it.

After fooling around to figure the above out, I've since found out that
the BlocksPerTrack is really 34.  I don't believe this is a problem as
it's a SCSI disk and it does as it pleases.  The numbers in the mountlist
are just to calculate the actual sectors numbers.

If you use 34, remember to cut each Lo/Hi cylinder in half, as 

(HiCyl-Locyl)*BlocksPerTrack*Surfaces have to equal the # of sectors
on the disk.  That assumes that you only make one partition, in my case
you'd have to change all three partitions.   Be sure to make BlocksPerTrack
the same for all partitions on the same physical disk ...

				Hope this helps ...
