Option Values: Enabled

Help Text:
Enable or disable memory mapped I/O of 64-bit PCI devices to 4 GB or greater
address space.
Comments: When enabled, PCI/PCIe Memory Mapped I/O for devices capable of 64-bit
addressing is allocated to address space above 4GB, in order to allow larger allocations and
avoid impacting address space below 4G.
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.
