Option Description
User Accessible Configures the user accessible USB ports. Selecting Only Back Ports On disables the front USB ports; selecting
USB Ports All Ports Off disables all front and back 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.
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.
Embedded NIC1
and NIC2
Enables or disables the Embedded NIC1 and NIC2 options. If set to Disabled, the NIC may still be available for
shared network access by the embedded management controller. The embedded NIC1 and NIC2 options are only
available on systems that do not have Network Daughter Cards (NDCs). The Embedded NIC1 and NIC2 option is
mutually exclusive with the Integrated Network Card 1 option. Configure the Embedded NIC1 and NIC2 option by
using the NIC management utilities of the system.
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 Enables or disables the use of Embedded Video Controller as the primary display. When set to Enabled, the
Controller 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.
Current State of Displays the current state of the embedded video controller. The Current State of Embedded Video Controller
Embedded Video option is a read-only field. If the Embedded Video Controller is the only display capability in the system (that is, no
Controller 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 Disabled.
SR-IOV Global Enables or disables the BIOS configuration of Single Root I/O Virtualization (SR-IOV) devices. This option is set to
Enable Disabled by default.
Internal SD Card Enables or disables the internal SD card port of the Internal Dual SD Module (IDSDM). This option is set to On by
Port default.
Internal SD Card Configures the redundancy mode of the Internal Dual SD Module (IDSDM). When set to Mirror Mode, data is
Redundancy 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 By default, the primary SD card is selected to be SD Card 1. If SD Card 1 is not present, then the controller selects
Card SD Card 2 to be the primary SD card.
OS Watchdog If your system stops responding, this watchdog timer aids in the recovery of your operating system. When this
Timer 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.
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 Disabled by default.
Memory Mapped Enables or disables the support for the PCIe devices that need large amounts of memory. Enable this option only
I/O above 4 GB for 64-bit operating systems. This option is set to Enabled by default.
NOTE: The Internal SD Card Port on the PCIe riser is controlled by Internal USB Port.
NOTE: The Embedded NIC1 and NIC2 options are only available on systems that do not have Integrated
Network Card 1.
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.
