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.
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.
Internal USB Port
Enables or disables the internal USB port. This option is set to
Enabled
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
Enable
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.
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 pre-boot 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 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.
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 require large amount 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 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. 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,the Option
ROM drivers are disabled. Only slots that are present on the system will be available for control.
