Oh, just so you know, your PC may only read 3.5 or whatever, but it can still fully use the 4 gigs if I remember correctly.
I guess you didn't read my post huh? Yes microsoft has a "fix" for this. Let me in on there secret, they no longer read the addressed memory for the memory total, they read the system memory and pop that in. It is only a visible change, they did nothing to make it access that memory.
And for your last part, no, the operating system can only read memory that has been addressed so it will not be used.
