V/AT Ver. 2.4 has a limit of 64 sectors/track hard coded into it. I thought
that the Perstor required that you set your drive type to 0 in CMOS. If that
is the case then V/AT will assume that no drive is installed. If that is not the
case and the controller is register level compatible with the WD1003 then there 
is no reason for it not to work.
