Perhaps you read that I encountered similar problems while trying to
bring up a SQ555 under Minix. Here is what I have done:
Minor device no.: 0-15 for HD 0 Controller 0
                 16-32 for HD 1 Controller 0
                 33-47 for HD 0 Controller 1 ...
So I used 34 and 35 for the first and second partition on the second
drive, and it worked - at least for normal (cp, mv, open, close write)
access. But there still were some problems with fsck, readall and such.
But there is a patch from Frans Meulenbroeks relative to 1.5.10.3.
Since some more people seem to have difficulties, I post it here once
again, just to increase bandwidth.
