I have two Conner IDE drives on my system (80MB and 100MB), and I have
found that they work fine with SCO Xenix/V-386 (releases 2.1, 2.3), and
Esix V/386 Rev.D.  My 386 has AT-bus, and the only problem I ever had
was when I increased the bus speed.  I'm not sure if this was because of
the `controller' or the drive electronics.

BTW, does anyone have any information regarding the logical
head/cylinder/sectors configuration of the various Conner IDE drives?
Since I didn't get any docs with the drives, I had to use trial-and-error.
