Does ESIX still not support RLL?

Once again, (no flame intended) all the MFM controllers I've seen use 
no more than 17 sectors per track.  All the RLL, ARLL, and other types
use more than 17.  So Esix has no way of knowing how you encode the data on
the disk... it does expect up to 17 sectors/track on standard PC controllers
for ST412/506 controllers.

The method of writing bit patterns is totally hidden from the OS.  That IS a
controller function.  You're correct.  However, they're very careful to say
that they don't support anything other than MFM type ST412/506 controllers.

They are just saying buyer beware to all of us with non WD1002/3 type controllers
for ST412 drives.

I'm checking with Perstor about my controller revs and it's suitability with
ESIX.
