This is incorrect.  The WD7000 FASST card operates in two modes.

1. The SSI mode in which it requires the special DOS drivers that you
   talk about.

2. The OEM mode in which it operated without any device drivers in
   much the same way I suspect as the AHA CARD.

I am using the card in the OEM mode and it works just fine.
