Hi
There is a table that one stores the step rate
for the drive. You need to alter the value for
slower drives, like your 8 inch. I forget where
is it but it is in that lower area someplace
( 40:xxx or something ). It isn't a problem
of the controller. It should work with any controller,
you just need to find the table and change it.
It has been a while since I've fiddle with it
to make my drives step with less noise ( and wear ).

Um, I'm not sure. I'm not sure I understand the question either. This is
a standard ISA IDE+floppy controller. Should I try an older one? Or hook
this up to an oldr PC from the 1980s?
If I then try to DIR the disk the head backs up a
track or so but can't
seem to recalibrate to track 0. The head vibrates as if the drive is
sending the signals to the stepper to retract the head but it only manages
to move back a track or so each time I issue DIR. If I do it enough it
eventually gets back to the stop position but it still gets sector errors.
Wrong step rate! Poke a new on eint othe chip, or does it use the old
table of junk INT 13h used to supoprt?
