I am running a 2372B with two 1024 * 8 head drives (Micropolis and
Miniscribe) with the drives set up as type 1.  I have an option in
the AMI BIOS (drive type 47) which is user definable (heads, cyl, precomp,
etc..) and when disabling the firmware on the controller and using
the drives as drive type 47 I have noticed no increase in IO - am I 
missing something?
