Memory switch question

[hennessy1]

I know that the 32bit xp pro has a 3gb memory switch and i heard that xp pro 64 has a 4gb switch or something like that (i.e. LARGEADDRESSAWARE) how do I enable that? (a little noobish at this sorry)

32-bit Windows kernel does have a 3GB switch to change the VM split from 2:2 to 3:1 but there is no such thing as a 4GB switch since the VM split on the 64-bit system is so much larger it's not needed right now. And chances are that the switch doesn't do what you think it does anyway, what are you trying to accomplish?
