Internal Graphics Mode Allows you to determine whether to allocate system memory for the onboard graphics controller. Disabled Disables the onboard graphics controller. UMA Allocates memory for the onboard graphics controller from the system memory. (Default) UMA Frame Buffer Size Frame buffer size is the total amount of system memory allocated solely for the onboard graphics controller. MS-DOS, for example, will use only this memory for display. Options are: Auto (default), 128MB, 256MB, 512MB. Surround View Enables or disables the Surround View function. This option is configurable only if Init Display First under Advanced BIOS Features is set to PEG and an ATI graphics card is installed. (Default: Disabled) Onboard VGA output connect Specifies the graphics display of the onboard graphics output from the D-SUB/DVI-D or D-SUB/HDMI. Auto BIOS automatically determines the primary display port for output, depending on to which port the display device is connected, D-SUB/DVI-D or D-SUB/HDMI. (Default) D-SUB/DVI Sets the D-SUB/DVI-D as the graphics display. D-SUB/HDMI Sets the D-SUB/HDMI as the graphics display.
