After I installed a driver update to Windows XP for the AMD 64 processor XP will not start. Safe Mode does not work. The "Last Known Good Configuration" does not work. The hardware appears ok since I'm now running the machine off of Knoppix. I seemed to have found the 4 files in WIndows/System 32. Any suggestions on rolling back a driver or using regedit in Wine? I'm using Wine 0.9. Thanks, JFK
