I would recommend getting XP final (2600 corperate doesn't require activation) instead of using a beta release. Or, if you feel you must use what you have, go into your configuration settings and tell it not to reboot on a BSOD, and log the faults to a text file for examination.

Also, try running in 'compatability mode' as Windows 98 or 2K. I have very few problems with XoloX, and never experience reboots because of it.
