laptop shared video memory

I just got a dell 1501 and it has an integrated ato xpress 1150.it has shared memory,is there any way of changing how much memory can be allocated to the card.I cant find a setting for it in the bios.does anyone know how to do it.
Thanks
Dave

 

it would be in the bois, just do a bit more searching

 

searched for ages,the bios is really basic,maybe dell dont let you change it

 

I think it's usually automatic and not configurable, i.e. in windows it'll use less, and in games use more.
