Regarding your recipe for installing a big disk (i.e. >1024 cyls):

You didn't say which flavor of unix you were installing.  Not turning on 
the disk adapter's translation feature may have been a mistake depending 
on which flavor and release of unix you installed.  You should be aware 
that some releases of unix/386 won't boot a kernel if any part of it is 
stored at or above cylinder 1024 (zero based).  You may not notice this 
bug for a very long time because all flavors of unix/386 now seem to 
have faster-file-gizmos which seem to always allocate blocks starting at 
the low end of the disk.  

Some unix vendors have fixed their bootstraps but I wouldn't be able to 
tell you for certain in which releases these bug-fixes appeared.  I 
think the latest and greatest versions of ISC and SCO may have this 
fixed.  I don't know about AT&T, Intel, and Esix.  The release notes for 
systems which have this bug usually mention the problem.
