Option Description
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 Enabled .
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 MicroSD
Card Port Enables or disables the internal MicroSD card port of the Internal Dual SD Module (IDSDM). This option is set to
On by default.
Internal MicroSD
Card Redundancy Configures the redundancy mode of the Internal Dual SD Module (IDSDM). When set to Mirror Mode, data is
written on both SDMicroSD 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 MicroSD card is visible to the OS. This
option is set to Disabled by default.
Internal microSD
Primary Card When Redundancy is set to Disabled , either one of the MicroSD card can be selected to present itself as mass
storage device by setting it to be primary card. By default primary MicroSD card is selected to be SD Card 1. If
MicroSD Card 1 is not present, then the controller will select MicroSD Card 2 to be the primary MicroSD card.
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.
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 above Base When set to 12 TB , the system will map MMIO base to 12 TB. Enable this option for an OS that requires 44 bit
PCIe addressing. When set to 512 GB , the system will map MMIO base to 512 GB, and reduce 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 Bifurcation Allows Platform Default Bifurcation , Auto discovery of Bifurcation and Manual bifurcation Control . The default
is set to Platform Default Bifurcation . The slot bifurcation field is accessible when set to Manual bifurcation
Control and is grayed out when set to Platform Default Bifurcation or Auto discovery of Bifurcation .
