The name's Melvarius (FYI my nickname from my unreal tournament days which has kinda stuck with me ) and thanks to this wonderful knowledge base I've successfully modded my bios with a SLIC 2.1. and I'm running windows7 ultimate. I've also modded a few friends machines as well. The motherboards have all been from ASRock and had AMI bios' so the process was relatively straight forward, thanks to some wonderful tools found on here. Motherboards modded to SLIC 2.1 so far are :- 775i65G (My Mobo) P4VM800 G31M-GS Looking forward to getting my teeth into some of the more challenging mods i've seen posted on the forum. Hope to see you around. Melvarius
