I'd recommend reading about it - read more than 1 article. Google "windows xp /3gb switch". I'm not sure it's a good idea, at least for me with my 4GB of physical RAM. It's a bit technical but there seems to be a reason why XP by default allocates its resources the way it does.
You make the change by editing a little text file that's read every time you boot the computer. If you decide to try this be sure to edit in such a way that you give yourself an alternative - in other words, that if the system fails to boot one way, it will automatically roll over and boot the other way. If you edit the .ini file wrong or have a problem - for example, a driver conflict - your computer might simply NOT startup at all, at least from what I have read tonight.
It's an interesting suggestion, though. I'm going to ask over at Adobe forums if I would see any benefit in Lightroom 2.5 if I did this....
