I don't know if it's normal or not. without a menu to switch graphics After several days of testing Now I need to disable ATI Mobility Radeon HD 4570.and enable intel HD Graphics integrated

I know, I know. Advanced BIOS is almost useless. There's really no menu to switch graphics and it can not be added as I don't know if a proper variable for this even exists in your BIOS.
