OK, I think I know what happened. I had a *Symbios* card, with an '825D
on it, which gave me wide differential with decent performance, and worked
well with our ncr driver. Although I saw the "Symbios" on the card, I've
seen dec modules with "Symbios" on them, so I managed to misclassify it
in my memory...

I believe I got it from here:
