I bought a Microsoft Comfort Curve 2000 keyboard and on my Vista machine it is not recognized until I get to the welcome screen. That means I can not access the mb bios, Acronis True Image menu or tyhe safe mode menu. My other IBM keyboard has no such issue. Funny thing is that this is connected to a KVM and on the other PC that has XP on it I get no such issue with the same keyboard. I guess this is a mb issue or is it possible that it is a Vista issue of some kind?
