I have created a 157mb windows xp pro setup WOW thats small. The only thing is tho it has nothing in it but bear needed stuff. I am going to run media engine, phidget kit and streets and trips. I have delete all the plug and play hibra files, and all drivers, fonts and other crap i didnt need. loaded the drivers that came with my board and some other things. So far its running good but i have to test some more.
