Option
Description
The USB keyboard and mouse function in certain USB ports during the boot process, depending on the selection.
After the boot process is complete, the USB ports will be enabled or disabled as per the setting.
Internal USB Port
Enables or disables the internal USB port. This option is set to
On
or
Off
. This option is set to
On
by default.
NOTE:
The Internal SD Card Port on the PCIe riser is controlled by Internal USB Port.
iDRAC Direct USB
Port
The iDRAC Direct USB port is managed by iDRAC exclusively with no host visibility. This option is set to
ON
or
OFF
. When set to
OFF
, iDRAC does not detect any USB devices installed in this managed port. This option is set
to
On
by default.
Integrated RAID
Controller
Enables or disables the integrated RAID controller. This option is set to
Enabled
by default.
Integrated
Network Card 1
Enables or disables the integrated network card (NDC). When set to
Disabled
, the NDC is not available to the
operating system (OS). This option is set to
Enabled
by default.
NOTE:
If set to Disabled (OS), the Integrated NICs might still be available for shared network
access by iDRAC.
I/OAT DMA
Engine
Enables or disables the I/O Acceleration Technology (I/OAT) option. I/OAT is a set of DMA features designed to
accelerate network traffic and lower CPU utilization. Enable only if the hardware and software support the
feature.This option is set to
Disabled
by default.
Embedded Video
Controller
Enables or disables the use of Embedded Video Controller as the primary display. When set to
Enabled
, the
Embedded Video Controller is used as the primary display even if add-in graphic cards are installed. When set to
Disabled
, an add-in graphics card is used as the primary display. BIOS will output displays to both the primary
add-in video and the embedded video during POST and pre-boot environment. The embedded video is disabled
before the operating system boots. This option is set to
Enabled
by default.
NOTE:
When there are mult iple 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 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
Disabled
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.
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
, th e 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
Enabled
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 red uces 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.
