Revision 1.3
If there is no add-in video card in any PCIe* slot connected to CPU Socket 1 with the Legacy VGA Socket
option set to
CPU Socket 1
, this option is set to
Disabled
and grayed out and unavailable.
If there is no add-in video card in any PCIe* slot connected to CPU Socket 2 with the Legacy VGA Socket
option set to
CPU Socket 2
, this option is set to
Disabled
and grayed out and unavailable.
If the Legacy VGA Socket option is set to CPU Socket 1 with both Add-in Video Adapter and Onboard Video
Enabled, the onboard video device works as primary video device while add-in video adapter as secondary.
2. 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 and default as
Disabled.
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 and is set to its default value of
Enabled
.
3. 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 has one processor installed on CPU
Socket 2 and can potentially have 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.
