Server Board Video and Add-In Video Adapter Support
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 active under an operating system 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 processor socket board. Some
multi-socket boards have PCIe* slots capable of hosting an add-in video card that is attached to the IIOs of
processor sockets other than processor Socket 0. However, only one processor socket can be designated as
a legacy VGA socket as required in POST. To provide for this situation, 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 1.
•
Because the onboard video is hardwired to CPU 0, when
Legacy VGA Socket
is set to
CPU Socket 1
,
the onboard video is disabled.
