Hmmm.... the entire reason I switched from an IDE drive to a SCSI
drive in a DOS machine was to allow connection of various peripherals
such as MO, Tape, DAT and stuff without having to get an adapter
and trying to figure out conflicting memory I/O addresses, IRQ's etc.
And I figured I didn't need bus mastering for a DOS machine so I
got a 1522 and sort of think support would be nice!
