Table 43. Integrated Devices details
Option Description
User Accessible USB Ports Configures the user accessible USB ports. Selecting Only Back Ports On
disables the front USB ports; selecting All Ports Off disables all front and
back USB ports. 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.
Internal USB Port Enables or disables the internal USB port. This option is set to ON by default.
iDRAC Direct USB Port The iDRAC Direct USB port is managed by iDRAC exclusively with no host
visibility. This option is set to ON or OFF. When set to OFF, iDRAC does not
detect any USB devices installed in this managed port. This option is set to On
by default.
Integrated RAID Controller Enables or disables the Integrated RAID Controller. This option is set to
Enabled by default. When set to Disabled the device is not visble to the
operating system
Embedded NIC1 and NIC2 Enables or disables the OS 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 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 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 is used as the primary display. BIOS will
output displays to both the primary add-in video and the embedded video
during POST and preboot 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 first card discovered during PCI enumeration is selected as
the primary video. You might have to rearrange 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 field. 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 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. 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 operating system. This option is set to Disabled by default.
Slot Disablement Enables or disables or boot driver disables the available PCIe slots on your
system. The slot disablement feature controls the configuration of the PCIe
cards 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 will be available
