Hey guys, I ran through this thread real quick and didn't catch anyone talking about locking the bios back up. Long story short, my concern is because I bough the 3 year extended accidental warranty on my new Y580 (which I got yesterday) that if I unlock the bios that I will void my warranty. Do they have any way of checking to see if the bios was tampered with or can I get a regular locked version of the bios back on the thing if I install an unlocked version on it? Lastly, my bios version is 3.7. Stupidly I deleted all partitions when formatting and installing windows 7 (cause windows 8 is useless to me...none of my FPGA programs run on it...nicely anyway) so I can't even go back and get a copy of it :-(, but not sure if it would matter reverting to an unlocked 2.06? I'm looking into seeing if there's a way I can snatch a copy of it still somehow. Thanks! --- Okay, not sure if it helps anyone or anything but I grabbed a copy of my bios if it does. Let me know if anyone wants it. I'm going to proceed to looking into modifying this version myself
