Sorry if you've > read the message before! Jeff - Did you re-seat the PCI Riser card? I've often found it to be the source of "strange" problems. I had one PCP/210 that I couldn't install all four screws that held the "floor" of the case in place, because it put the case in enough of a bind (out of square) that the riser card wouldn't seat (make correct contact in it's slot) and it acted similarly to yours. If I left out one screw (the *right* one), all was fine. How long do you think it took me to figure that one out? Re-seating the CPU - ROM - RAM - PCI cards - etc then hittin' the 'Cuda would all be a good idea, too. All the very conscious of upsetting the Riser. Re: Open Firmware - I've never heard OF spoken of in regards to any Mac previous to what's commonly referred to as OF Macs. (orig iMac, B&W-G3, etc and newer) - but I'm no geek, so I could be way off base. Please enlighten me. Hope you find help here.
