Table 21. Integrated Devices details(continued)
Option Description
can enable or disable the front ports dynamically by authorized user without resetting
the system. This option is set to All Ports On by default.
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. This option is set to On by default.
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. This option is set to
Enabled by default.
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
Enabled.
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. This option is set to Enabled by
default.
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 and 128K Cycles. This option is set to 2K
Cycles by default.
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 card
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. This option is set to Enabled 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 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. This option is set to Disabled by default.
