  There are several controllers for ESDI which look just like AT flavor
controllers and allow you to run standard AT Xenix/386. The Western
Digital is one, I *think* the number is 1007. Dell uses one in their
310/325 series (on which I type this).

  If money is a problem they also make the WD1006VSR2 RLL controller.
This has hardware track buffering and gives about the same performance
as the ESDI models, with cheaper hardware. If you need a lot of disk
ESDI is probably your best best.
