I missed the days of XP so for a bit fun I installed XP Media Center Edition 2005 on my mid 2009 17in Macbook Pro 3.06ghz 8GB. First off I am aware that 32bit systems only can access 4gbs as a max. I always used x64 systems (even back in the day XP x64 Edition) so when it comes to x86 I'm not the best at it. The system reports only total of 2.72Gbs available. I know that in "boot camp" my 9600m GT is being used. Since at first I amused that 9400m GT was being used and it was just using some of the system memory for graphics. So what would cause XP to report only 2.72Gbs? As you can see my screen shot.
