from what you're saying i think you've already done that
ie you've selected in your BIOS that you want to allocate more memory to graphics (stealing off your RAM). that's why it is saying total available is 287 ... if you want to check hit F2 at the BIOS screen and you can confirm how much you want to allocate. don't touch anything else unless you know what you're doing! then save and exit if you want to keep any changes.
i must say wont change much though, as on-board graphics arent usually the fastest to start off with, but may help.
