Hey, I have an nvidia geforece 7150LE with 128mb of dedicated memory...i heard that you can dedicate more memory to the card by going into BIOS, but my BIOS didn't have an option to do that (i was told to look for "UGA frame buffer size" or something like that). Anyone have any idea how to do this? I have an HP m8120n, if it helps determine what BIOS i'm running.

Oh...so to get this straight, on my old computer, which has Intel integrated graphics, I would be able to dedicate more memory through the BIOS, but not with a graphics card, right?

Also if I understand right the reason is because the memory is the system ram being shared. So if you 512 MB of system ram and you dedicate 64 MB of ram for video the system can only use 448 MB for itself.
Normal graphics cards use their own memory which is not only more efficient it lets the system use all the system ram available.
