Changing shared memory on Acer Aspire One

[diazdavenator]

I got an Acer Aspire One netbook for my birthday a couple weeks ago and I've been trying to figure out how to change the shared video memory from 8 MB to 64. I tried going into the BIOS to change it, but the option was not changeable. Has anyone else tried doing this? If so, what do I need to do to change it?

Thanks
