Integrated Devices

Use this window to control devices integrated on the system board.

NOTE: The help page may include information about features and values that are not supported on your system. Server Administrator displays only the features and values that are supported on your system.

NOTE: For more details on user privilege levels, see Privilege Levels In The Server Administrator GUI.

User Accessible USB Ports

Configures the User Accessible USB Ports. The USB keyboard and mouse devices functions in certain USB ports during the boot process, depending on the selection. After an operating system driver is loaded, the USB ports are enabled or disabled as per the field's setting.

All Ports On Enables both front and back USB ports.
Only Back Ports On Disables front USB ports.
All Ports Off Disables both front and back USB ports.
All Ports Off (Dynamic) Disables all front and back USB ports during the POST and front ports can be enabled or disabled dynamically by authorized user without resetting the system.

Internal USB Port

Enables or disables the internal USB port.

iDRAC Direct USB Port

The iDRAC Direct USB port is managed by iDRAC exclusively with no host visibility. When set to Off, iDRAC does not detect any USB devices that are installed in this managed port.

Embedded NIC

Enables or disables the operating system interface of the embedded NIC controller.

NOTE:  If set to Disabled (operating system), the embedded NICs may still be available for shared network access by the embedded management controller. Configure this function via the NIC management utilities provided with your system.

Embedded NIC Port (n) Boot Protocol

A write-only attribute to control the Legacy Boot Protocol of the LOM port that is specified by the embedded NIC port number. This attribute always returns Unknown when read.

NOTE: This attribute is for system management software use and does not appear in the system BIOS setup.
Table 2. Embedded NIC Port (n) Boot Protocol
Unknown No change to the LOM Port Legacy Boot Protocol setting
None An error is returned with one of these settings that is not supported by the LOM port.
PXE
iSCSi

I/OAT DMA Engine

Enables or disables the I/O Acceleration Technology (I/OAT) option. Enable this feature only if the hardware and software support I/OAT.

Embedded Video Controller

Enables or disables the use of the Embedded Video Controller. BIOS output displays to both the primary add-in video and the embedded video during POST and pre-boot environment. The embedded video is disabled right before the operating system boots.

NOTE: When there are multiple add-in graphics cards that are installed in the system, the first card that is discovered during PCI enumeration is selected as the primary video. Rearrange the cards in the slots in order to control which card is the primary video controller.
Enabled When the option is set to Enabled, the Embedded Video Controller is the primary display even if add-in graphics cards are installed.
Disabled When the option is set to Disabled, an add-in graphics card is used as the primary display.

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 helps to improve performance on workloads where throughput and latency are critical.

SR-IOV Global Enable

Enables or disables BIOS configuration of Single Root I/O Virtualization (SR-IOV) devices. Set this option to Enabled to boot to a Virtualization operating system that recognizes SR-IOV devices.

OS Watchdog Timer

If the system stops responding, the watchdog timer helps in the recovery of the operating system.

Enabled The operating system allows to initialize the timer.
Disabled (default) The timer has no effect on the system.
NOTE: If the operating system Watchdog Timer is Enabled, you cannot perform recover actions on the system using the BMC Watchdog Timer.

Empty Slot Unhide

When set to Enabled, root ports of all the empty slots are accessible to the BIOS and the operating system.

Memory Mapped I/O above 4 GB

Enables or disables support for PCIe devices that require large amounts of memory.

NOTE: This option is applicable only for 64–bit operating systems.

Memory Mapped I/O Base

56 TB MMIO base default. User should not change the default value unless addressing a known issue.
12 TB The system maps MMIO base to 12 TB. Enable this feature for an operating system that requires 44-bit PCIe addressing.
512 GB The system maps MMIO base to 512 GB, and reduces the maximum support for memory to less than 512 GB. Enable this option only for the four GPU DGMA issue.

Slot Disablement

The Slot Disablement feature controls the configuration of PCIe cards that are installed in the specified slot. Only slots that are present on your system is available for control.

NOTE: Slot 1—Slot 10 are available but hidden if corresponding slot does not exist in the system.

Integrated RAID Controller

Enables or disables the integrated RAID controller.

USB 3.0 Settings

This option enables or disables the USB 3.0 support.

Enabled When the option is set to Enabled, the BIOS enables USB 3.0 ports after the operating system boots. Choose this option only if your operating system has native USB 3.0 drivers support, otherwise devices work after booting to the operating system.
Disabled When the field is set to Disabled (default), the USB devices operate at USB 2.0 speed.

Internal SD Card Port

Enables or disables the internal SD Card Port.

Internal SD Card Redundancy

Disabled Only SD card 1 is visible to the operating system.
Mirror Data is written to both SD cards. On 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.

Internal SD Primary Card

This field selects which SD card is a primary SD card.

I/O Non-Posted Prefetch

Enables or disables the I/O non-posted prefetch. The PCIe throughput reflects the changes in this field.
