3. Onboard Video
Option Values: Enabled
Disabled
Help Text:
On-board video controller.
Warning: System video is completely disabled if this option is disabled and an add-in video
adapter is not installed.
Comments: When disabled, the system requires an add-in video card for the video to be seen.
When there is no add-in video card installed, Onboard Video is set to Enabled and grayed out so it
cannot be changed.
If there is an add-in video card installed in a PCIe slot connected to CPU Socket 1, and the Legacy
VGA Socket option is set to CPU Socket 1, then this Onboard Video option is available to be set.
If there is an add-in video card installed on a PCIe slot connected to CPU Socket 2, and the Legacy
VGA Socket option is set to CPU Socket 2, this option is grayed out and unavailable, with a value set to
Disabled. This is because the Onboard Video is connected to CPU Socket 1, and is not functional when
CPU Socket 2 is the active path for video. When Legacy VGA Socket is set back to CPU Socket 1, this
option becomes available again, set to its default value of Enabled.
Note: This option does not appear on some models.

4. Legacy VGA Socket
Option Values: CPU Socket 1
CPU Socket 2
Help Text:
Determines whether Legacy VGA video output is enabled for PCIe slots attached to Processor
Socket 1 or 2. Socket 1 is the default.
Comments: This option is necessary when using an add-in video card on a PCIe slot
attached to CPU Socket 2, due to a limitation of the processor IIO. The Legacy video device can be
connected through either socket, but there is a setting that must be set on only one of the two. This
option allows the switch to using a video card in a slot connected to CPU Socket 2.
This option does not appear unless the BIOS is running on a board which have one processor installed
on CPU Socket 2 and can potentially a video card installed in a PCIe slot connected to CPU Socket 2.
This option is grayed out as unavailable and set to CPU Socket 1 unless there is a processor installed
on CPU Socket 2 and a video card installed in a PCIe slot connected to CPU Socket 2. When this
option is active and is set to CPU Socket 2, then both Onboard Video and Dual Monitor Video are set to
Disabled and grayed out as unavailable. This is because the Onboard Video is a PCIe device
connected to CPU Socket 1, and is unavailable when the Legacy VGA Socket is set to Socket 2.
