There are (at least) two things you must do to make a SCSI drive run in
enhanced mode.

1.	You must run Smartdrive (it does some double buffering that is
needed for bus mastering controllers)

2.	In [386enh], in system.ini, you must have the line

	VirtualHDIRQ=False

As a side note, I could not load smartdrive high with QEMM on my SCSI system.
