Brand name 'eh?
I wonder how brandname it has to be. The company that made my PC
www.abspc.com even had their own WinXp Cd version. said it was from Magnell or something. I upgraded the HD, the graphics card, new higher DDR ram, and all the optical drives. Works fine. Oh the same CD and serial allowed me to upgrade from Win 2k to XP and install SP 1 on my dell laptop. Not that I didnt legally purchase a seperate copy of XP for my laptop or anything.
But do the big name vendors such as dell put much higher restrictions on theirs?
