That depends, does your video card use shared video memory? You can
find that in the BIOS as normally you can adjust that down if you need
to conserve RAM for non-video needs.
A lot of laptops do that, but I don't know that all of them do. Mine
does not, but yours might be different.
If it's NOT shared memory, then you're only seeing 3.5GB on the 32bit
system. However, I'd be willing to bet that you ARE using shared memory,
as typically a 32-bit system sees 3.7 to 3.8GB of RAM our of 4GB.
