The 1024 cylinder limitation is not an AT&T invention.
Complain to your vendor.
AT&T Unix sVr3.2 and sVr4.0 (at least the beta i have seen)
have no problems with drives with more than 1024 cylinders,
without the need for funny translation procedures.
I have used a CDC Wren V (383H) with 1224 cylinders and an
Adaptec 2322 controller with both versions of Unix and never had
any problem. ISC 2.0.1 (but i believe later versions have the same
problem) decided (wrongly!) that my system would not support more
than 1024 cylinders and would not let me access the last 200 cylinders.
