So how did you do it? I told it to use up to cylinder 1223 (the last one
on my disk) and ISC 2.0.1 complained and told me my system did not support
more than 1024 cylinders and it changed the last cylinder back to 1023.

I didn't give up that easily. I went back to AT&T sVr3.2 and partitioned
the disk so now I had the correct Unix partition. I interrupted the
AT&T installation, went back to ISC, and skipped the partitioning step
(since I already had a Unix partition). Shortly thereafter the system
promptly crashed (panic). For some reason 2.0.1 did not like my partition
that went up to cylinder 1223. (I have tried with a partition to 1023
and 2.0.1 did install.) Needless to say I trashed the 2.0.1 and went back
to AT&T Unix, which happily uses all cylinders up to 1223.

Maybe there is a problem because of the Adaptec 2322 controller?

Paul.
