I picked up this XL a few years back and can only get it to start up if I plug the IO board straight into the motherboard. If I use the riser board, doesn't start up. But, can't close the case with the IO board sticking straight out the back, so I've been trying to find a Telco Riser Board (with no luck so far).
Ha, laughs on me...
Pulled the IO board out, gave the connectors on both the IO Board and the Riser Board a light sanding w/600 grit, wiped them clean w/naptha, plugged them back in, and it started.
Now tells me that I've got an "Invalid Key", but that's a whole lot farther along than I was earlier. Crap... and to think this has been sitting here next to my desk for ~2yrs and all I needed was to clean off the bloody connectors. Sigh...
Well, now I need to sort out what's wrong with the CD/Key I've got here, but I'll figure that out when I'm back from vacation at the end of the month.
