i have a pavillion g6 notebook working on a windows 8 os and my dedicated memory is 32 mb while my available is 1664mb and i dont know how to access my bios and also change my vram dedication
Most likely in the advanced settings menu area. I don't have the BIOS layout, so I can't tell you precisely. Look through all of the menus and see if it's there--something like Shared Video Memory or the like.
