To provide for this, there is another PCI Configuration option to control “Legacy VGA Socket”.
The rules for this are:
This option appears only on boards which have the possibility of an add-in video
adapter in a PCIe slot on a CPU socket other than socket 1.
When present, the option is grayed out and unavailable unless an add-in video card is
actually installed in a PCIe slot connected to the other socket.
Because the Onboard Video is “hardwired” to CPU Socket 1, whenever Legacy VGA
Socket is set to a CPU Socket other than Socket 1, that disables both Onboard Video.

Dual Monitor Video
The BIOS supports single and dual video on the S2600 family of Server Board when add-in
video adapters are installed. Although there is no enable/disable option in BIOS screen for
Dual Video, it works when both “Onboard video” and “Add-in Video Adapter” are enabled.
In the single video mode, the onboard video controller or the add-in video adapter is detected
during the POST. In the dual video mode, the onboard video controller is enabled and is the
primary video device while the add-in video adapter is allocated resources and is considered
as the secondary video device.

Configuration Cases – Multi-CPU Socket Boards and Add-In Video Adapters
Because this combination of CPU Socket and PCIe topology is complicated and somewhat
confusing, the following set of “Configuration Cases” was generated to clarify the design.
When there are no add-in video cards installed...
Case 1: Onboard Video only active display.
Onboard Video = Enabled (grayout, can't change)
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Disabled (grayout, can't change)
When there is one add-in video card connected to CPU Socket 1...
Case 2: Onboard video active display, add-in video doesn't display.
Onboard Video = Enabled
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Disabled
Case 3: Add-in video active display, onboard video doesn't display.
Onboard Video = Disabled
Legacy VGA Socket = CPU Socket 1 (grayout, can't change)
Add-in Video Adapter = Enabled
