Finally!  A question that I can answer to repay all of you who have helped
me!  I'm using a 110MB IDE drive under Minix 1.3 right now.  I didn't have
to make much in the way of changes - none that are really related to IDE.  The
IDE controller interface is the same as an AT.  BUT, I had to change the number
of heads/cylinders in fsck, fdisk, and others?  And, since my controller puts
the int41H/int46H drive parameter table in the "reserved" interrupt space, 
I had to make a copy of the table for minix before minix overwrites it.  Glen
Overby tells me that he fixed most of this in 1.5.  Also, in 1.3, I could only 
get about 30K blocks on a drive, and minix won't allow you to mount more than
one of those since there are bugs in the buffer handling routines.  Glen 
fixed that in 1.5 also.  I'm slowly working up to 1.5.10, and will report back 
when I get there.  If you have more questions, please ask!  My drive is a
Imprimis drive, but I suspect that all the IDE drives of this size have a
similar interface.  -Scott
