i have an acer aspire 5749, it has built in Intel HD 3000 graphics. i was made aware that only 128mb of that is used for video graphics, and that this could be changed in the bios settings. however i am unable to find anywhere how to change my bios settings, as in the bios setup utility it has video memory fixed. was wondering if someone could edit a bios i could flash? or point me in the right direction. thanks for your help in advance
