I have few questions guys, please help. I'm currently using the 1.5 official BIOS with X2 550. When I tried to unlock the CPU using "special" and "Auto", my system won't boot at all, even when I set the voltage to 1.4V. Can the official 1.5 BIOS unlock the dual core or do I just have a bad CPU?

I also had a bad flash going from 1.3 to 1.5 using M-Flash, the flash was successful according to M-Flash but the board won't boot anymore after that. I had to send the board back to MSI for reflash so now I'm afraid to play around with the BIOS again especially when the BIOS is a beta version. How did you guys flash your boards and how many of you came across a bad flash on this board?
