The CF-29's use a Pentium M, that is a 32 bit only processor.
Personally I dual booted XP with Ubuntu. If you use Linux and want to run windows programs you will need WINE. Ubuntu comes with open office a windows office alternative. Ubuntu 10.10 worked really well I haven't really tried any of the newer versions on it.http://forum.notebookreview.com/panason ... rsion.html
Windows 7 will work but will use more resources to run than XP unless you tweak it, that goes for drivers as well.
I am sure someone can point you in the right direction for restore disks. If now do you have anyother OEM restore disks lying around?
The BSOD was caused by chip-set being different this model uses DDR2 ram, an upgrade from Mk3 and older DDR ram. You could try un-installing the chipset driver and other specific drivers that deal with cpu, etc. Then when windows start looking quickly power off and swap to the newer CF-29. Intel 855GME Mk3 vs Intel 915GMS on the and video. I have had this work on some pc's since you are still using a Pentium M in the same family. When too much hardware changes windows anti-piracy kicks in and BSOD.
