Increasing system RAM used by my Integrated video card.?

How can i do that? i have 4 gigs of ram and i was wondering how i could increase the system ram beings shared with my integrated card?

Thanks|||The option is usually in your BIOS- how much memory is allocated to the onboard video. Doesn't make the card any faster, though. Even a $50 dedicated card like a Geforce 7300GT is better than any integrated video.|||The integrated card has a max on the ammount it can share with RAM. That max is reached when the graphics need more v-ram it automatically pulls it from your system ram.
