Option	Description
User Accessible USB Ports	Configures the user accessible USB ports. Select Only Back Ports On to disable the front USB ports. Select All Ports Off to disable all front and back USB ports. Select All Ports Off (Dynamic) to disable all front and back USB ports during POST. You can enable or disable the front ports dynamically by authorized user without resetting the system. By default, this option is set to All Ports On.
User Accessible USB Ports	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.
iDRAC Direct USB Port	iDRAC exclusively manages the iDRAC Direct USB port with no host visibility. You can set this option to ON or OFF. When set to OFF, iDRAC does not detect any USB devices that are installed in this managed port. By default, this option is set to On.
Integrated Network Card1	Enables or disables the integrated network card. When this option is set to Disabled, the card is not available to the operating system. NOTE: If set to Disabled (operating system), the Integrated NICs might still be available for shared network access by iDRAC.
Embedded NIC1 and NIC2	Enables or disables the operating system interface of the Embedded NIC1 and NIC2 controller. If set to Disabled (OS), the NIC may still be available for shared network access by the embedded management controller. Configure the Embedded NIC1 and NIC2 option by using the NIC management utilities of the system. By default, this option is set to Enabled.
I/OAT DMA Engine	Enables or disables the I/O Acceleration Technology (I/OAT) option. I/OAT are DMA features that accelerate network traffic and lower CPU utilization. Enable this option only if the hardware and software support the feature. By default, this option is set to Disabled.
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 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. The BIOS output displays to both the primary add-in video and the embedded video during POST and preboot environment. The embedded video is disabled right before the operating system boots. By default, this option is set to Enabled. NOTE:When multiple add-in graphics cards are installed in the system, the first card that is discovered during the PCI enumeration is set as the primary video. To control which card is recognized as is the primary video card, rearrange the cards in the slots.
I/O Snoop HoldOff Response	Selects the number of cycles PCI I/O can withhold snoop requests from the CPU, to allow time to complete its own write to LLC. This setting can help improve performance on workloads where throughput and latency are critical. The options available are: 256 Cycles 512 Cycles 1K Cycles 2K Cycles 4K Cycles 8K Cycles 16K Cycles 32K Cycles 64K Cycles 128K Cycles By default, this option is set to 2K Cycles.
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 option in the system and no other add-in graphics cards are installed, the Embedded Video Controller is automatically used as the primary display even if the Embedded Video Controller setting is set to Disabled.
SR-IOV Global Enable	Enables or disables the BIOS configuration of Single Root I/O Virtualization (SR-IOV) devices. By default, this option is set to Disabled.
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. Disabled (the default), the timer does affect on the system.
Empty Slot Unhide	Enables or disables the root ports of all the empty slots that are accessible to the BIOS and operating system. By default, this option is set to Disabled.
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 are available for control. When this option is set to boot driver disabled, both the Option ROM and UEFI driver from the slot do not run during POST. The system does not boot from the card, and the preboot services are not available. However, the card is available to the operating system.
Slot Disablement	Slot n: Enables or disables or only the boot driver is disabled for the PCIe slot n. By default, this option is set to Enabled.
Slot Bifurcation	Auto Discovery Bifurcation Settings allows Platform Default Bifurcation, Auto Discovery of Bifurcation, and Manual bifurcation Control.
Slot Bifurcation	By default, this option is set to Platform Default Bifurcation. The slot bifurcation field is accessible when set to Manual bifurcation Control and is unavailable when set to Platform Default Bifurcation and Auto Discovery of Bifurcation. NOTE: The slot bifurcation supports on PCIe slot only, does not support slot types from Paddle card to Riser and Slimline connector to Riser.
