Almost same thing
Have X3 installed on ver. 1.0 box, if I set any single bank switch to On and boot, I go to a FlashBios 3.0.0 screen. Backup bios, hold Power and eject when starting, is same 3.0.0. Made a 3.0.3 Bios DVD, do install from CD, shows bios is downloading. When I restart, still have 3.0.0. Any ideas?
