Righteo, my problem is this - i keep failing vista home premium because it needs 1gHz processor as a MINIMUM, well i have two 1.83 rigggght? (macbook NOT core2due) surley that means i have 3.32 (i think - terrible maths) so why am i failing a 1ghz minimum? very gutted. i think because im on bootcamp it can't run to the full potential (for instance, it says i have 998Mb ram when i have 1GB) but thats half an a wee bit less that what i have for processor, so i'm thinking only one of my processors is working through bootcamp? If i have got this all wrong just tell me, i'm not pretending to be a mac expert, i'm a total novice. thanks alot PS - in device manager it says i have 2 processors at 1.83, so they can both be seen!
