I'd gladly do this, but I though I'd ask for some direction before, 
since, right now, I have very few details.

Something in particular?
The only thing that comes to my mind is the following:

Oh, and I'm using gmirror with a couple of disks.
There's also a zip drive attached (which has always worked), but I've

the system paniced.

I have never seen any little trouble with such a card (I've had more 
than one here and at customers'); thought it might actually be dying, I 
really find it strange that it started as soon as I upgraded from 9.3 to
