- You might try setting your drive type in CMOS to NONE. I was able
- to use Western Digital 8 bit controller with an ST-251 in my 386
- by doing that. I am not sure why it works but my guess is that if the
- BIOS does not see a Hard Disk in it's CMOS table it looks for an XT
- controller (at segment C800) before assuming that the system only has
- floppies.
- While the XT controller can be made to work, performance is less
- than spectacular. In fact I found that while the optimum interleave
- for that drive/controller combination was 3:1 in an XT, I had to
- increase it to 5:1 in the 386. Perhaps someone on the net can explain
- that. You can get 16 bit 1:1 controllers for 45 or 50 dollars and the
- increase in performance is incredible. That might be the best thing
- to do.
- One other thing: If the drive has been used with another type of
- controller, you might have to do a low level format to get things
- going.
