Listen to Andy Hui, he knows his stuff. Your board just needs an updated bios and a late model slotket- some of the older ones don't support celly2's. Your board uses the late model via chipset, so it natively supports coppermines. Many older BX boards will support them, too, up to 1.1gig with the right bios and slotket. My old BH6 runs a 1gig CDO celly2 just fine- flashed the bios, set the slotket to auto- strictly P&P after that.
