+It runs just fine. By definition an IDE disk presents a standard ST506
+interface to the system. To Xenix/UNIX this just looks like a standard
+MFM or RLL disk. From throughput comparisons I've run on Quantum SCSI
+and IDE drives, the IDE drives have performance just slightly under the
+SCSI performance.

Same here; only caveat I'd like to add is that I've yet to get UNIX
(ESIX or Intel) to install on a system with IDE and a Phoenix BIOS, even
one with the user entered disk parameters.  No problems with AMI; using
disk type 47 and user entered parameters.  This is using Conner disk
drives, and any of the IDE interface on the MB, a Conner IDE to ISA
adapter, or a Miniscribe IDE to ISA adapter. 

The Conner 3204 is a fast little drive.
