Option
Description
embedded video will then be disabled right before the operating system boots. This
option is set to
Enabled
by default.
NOTE:
When there are multiple add-in graphic cards installed in the
system, the first card discovered during PCI enumeration is selected as
the primary video. You might have to re-arrange the cards in the slots in
order to control which card is the primary video.
Current State of Embedded Video
Controller
Displays the current state of the embedded video controller. The
Current State of
Embedded Video Controller
option is a read-only field. If the Embedded Video
Controller is the only display capability in the system (that is, no add-in graphics card
is installed), then the Embedded Video Controller is automatically used as the primary
display even if the
Embedded Video Controller
setting is set to
Disabled
.
PCIe Preferred IO Device
When set to
Enabled
, you can provide the Bus/device/function address (in decimal)
to choose end device for preferred IO device. This option is set to
Disabled
by
default.
SR-IOV Global Enable
Enables or disables the BIOS configuration of Single Root I/O Virtualization (SR-IOV)
devices. This option is set to
Disabled
by default.
Internal SD Card Port
Enables or disables the internal SD card port of the Internal Dual SD Module
(IDSDM). This option is set to
On
by default.
Internal SD Card Redundancy
Configures the redundancy mode of the Internal Dual SD Module (IDSDM). When set
to
Mirror
Mode, data is written on both SD cards. After failure of either card and
replacement of the failed card, the data of the active card is copied to the offline
card during the system boot.
When Internal SD Card Redundancy is set to
Disabled
, only the primary SD card is
visible to the OS. This option is set to
Mirror
by default.
Internal SD Primary Card
By default, the primary SD card is selected to be SD Card 1. If SD Card 1 is not
present, then the controller selects SD Card 2 to be the primary SD card. This option
is set to
SD Card 1
by default.
OS Watchdog Timer
If your system stops responding, this watchdog timer aids in the recovery of your
operating system. When this option is set to
Enabled
, the operating system initializes
the timer. When this option is set to
Disabled
(the default), the timer does not have
any effect on the system.
Empty Slot Unhide
Enables or disables the root ports of all the empty slots that are accessible to the
BIOS and OS. This option is set to
Disabled
by default.
Memory Mapped I/O above 4 GB
Enables or disables the support for the PCIe devices that need large amounts of
memory. Enable this option only for 64-bit operating systems. This option is set to
Enabled
by default.
Memory Mapped I/O Base
When set to
12 TB
, the system maps the MMIO base to 12 TB. Enable this option for
an OS that requires 44 bit PCIe addressing. When set to
512 GB
, the system maps
the MMIO base to 512 GB, and reduces the maximum support for memory to less
than 512 GB. Enable this option only for the 4 GPU DGMA issue. This option is set to
56 TB
by default.
Slot Disablement
Enables or disables the available PCIe slots on your system. The slot disablement
feature controls the configuration of the PCIe cards installed in the specified slot.
Slots must be disabled only when the installed peripheral card prevents booting into
the operating system or causes delays in system startup. If the slot is disabled, both
the Option ROM and UEFI drivers are disabled. Only slots that are present on the
system will be available for control.
Slot n
: Enables or disables or only the boot driver is disabled for the PCIe slot n. This
option is set to
Enabled
by default.
