Owners Manual

Option Description
User Accessible
USB Ports
Congures the user accessible USB ports. Selecting Only Back Ports On disables the front USB ports; selecting
All Ports O disables all front and back USB ports; selecting All Ports O (Dynamic) disables all front and back
USB ports during POST and front ports can be enabled or disabled dynamically by authorized user without
resetting the system.
The USB keyboard and mouse still 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 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 trac 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 rst 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 eld. 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 DisabledEnabled.
SR-IOV Global
Enable
Enables or disables the BIOS conguration 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
Congures 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 oine 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
When Redundancy is set to Disabled, either one of the SD card can be selected to present itself as mass storage
device by setting it to be primary card. By default primary SD card is selected to be SD Card 1. If SD Card 1 is not
present, then the controller will select 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, the operating system initializes the timer. When this option is set to Disabled (the
default), the timer does not have any eect 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
46 Pre-operating system management applications
