MrUser,

 This XPS should work. Have you gone to the following Msn site and checked for compatibility? Download the Advisor and it will check your machine and you can check compatibility  of other features of you machine. I'm using a XPS M2010 and it's not listed either but it's compatible and several have upgraded.

 You might want to read thru the attached forum on the m2010 to get some insight on the problems had on this system and drivers. It may help Do open the northernlights url to see the procedure for reference.

Good luck

Thanks belboy,

I ran the advisor and it did not report anything really worrying. I will go ahead and try.

Thanks. I will try installing next weekend. I will go back to that thread if I face any bluetooth problems. I have a PS/2 keayboard plugged in already, will find me a mouse too. I will start a new thread on to get some questions answered regarding Raid.
