I will soon be acquiring an 85 meg MFM hard drive which happens to have
1250 cylinders.  I have heard that the 'standard' Western Digital controller
for the PC/AT only supports up to 1024 cylinders.  Does anyone know of an
MFM controller which will allow me to utilize all 1250 cylinders?  The
controller must be Xenix compatible.

Also, what exactly is the difference between ESDI and the ST506 standard? Is
it possible to use an ST506 drive with an ESDI controller?

Thanks in advance.
