Option Description
by the embedded management controller. Configure the Embedded NIC1 and
NIC2Embedded NIC1 option by using the NIC management utilities of the
system.
Embedded Video Controller Enables or disables the use of Embedded Video Controller as the primary
display. When set to Enabled, the Embedded Video Controller will be the
primary display even if add-in graphic cards are installed. When set to
Disabled, an add-in graphics card will be used as the primary display. BIOS will
output displays to both the primary add-in video and the embedded video
during POST and preboot environment. The 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 that are installed in
the system, the first card discovered during PCI enumeration is selected as
the primary video. You might have to rearrange 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 I/O 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 operating system. 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.
Memory Mapped I/O Limit Controls where MMIO is mapped. The 1 TB option is designed for specific
operating system which cannot support MMIO over 1 TB. This option is set to 8
TB by default. The default option is the maximum address that the system
supports and recommended usually.
Slot Disablement Enables or disables the available PCIe slots on your system. The slot
disablement feature controls the configuration of the PCIe cards that are
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.
