are You from MSFT support ?
I am guessing, because the answer is correct but completely useless (at least for me)
I use 64 Bit Ubuntu Desktop, so the OS would be able to access it.
The question is, will the chipset recognise the 4GB Ram and will it be accessible, of course with a 64 Bit OS.
I know, the manual is showing 2GB max for that model, but I also know that this is sometimes not correct.
