Hi! Does anybody out there have any suggestion how to use the WD1006 (RLL, 1:1) Controller under 386/ix or 386/V ? I found out that Interleave 6 is the fastest one, but it is slower than using a regular WD1003 with interleave 2. So why does MS-DOS increase disktransfers by 3 when using the 1:1 interleave but 386/ix slows down rapidly ? cu, dirk :-)
