Onboard Video and Add-In Video Adapter Support
Add-in video cards can be used to either replace or complement the onboard video option of the server
board. BIOS setup includes options to support the desired video operation when an add-in video card is
installed.
•
When both the Onboard Video and Add-in Video Adapter options are set to Enabled, both video
displays can be active. The onboard video is still the primary console and active during BIOS POST;
the add-in video adapter is only be active under an OS environment with video driver support.
•
When Onboard Video is Enabled and Add-in Video Adapter is Disabled, only the onboard video is
active.
•
When Onboard Video is Disabled and Add-in Video Adapter is Enabled, only the add-in video
adapter is active.
Configurations with add-in video cards can get more complicated with a dual CPU socket board. Some multi-
socket boards have PCIe slots capable of hosting an add-in video card which are attached to the IIOs of CPU
sockets other than CPU Socket 1. However, only one CPU socket can be designated as legacy VGA socket as
required in POST. To provide for this, there is the PCI Configuration option Legacy VGA Socket. The rules for
this option are:
•
The Legacy VGA Socket option is grayed out and unavailable unless an add-in video card is installed
in a PCIe slot supported by CPU 2.
•
Because the onboard video is hardwired to CPU socket 1, when Legacy VGA Socket is set to CPU
Socket 2, the onboard video is disabled.

Dual Monitor Support
The BIOS supports single and dual video when add-in video adapters are installed. Although there is no
enable/disable option in BIOS setup for dual video, it works when both the Onboard Video and Add-in Video
Adapter options are enabled.
In the single video mode, the onboard video controller or the add-in video adapter is detected during POST.
In 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 during POST. The add-
in video adapter will not be active until the operating system environment is loaded.
