Description
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 n: Enables or disables or only the boot driver is disabled for the PCIe slot n. This
option is set to Enabled by default.
Auto Discovery Bifurcation Settings allows Platform Default Bifurcation, Auto
Discovery of Bifurcation, and Manual bifurcation Control.
This option is set to Platform Default Bifurcation by default. 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 type
from Paddle card to Riser and Slimline connector to Riser.
Description
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.
Selecting Only Back Ports On disables the front USB ports; selecting All Ports Off
disables all front and back USB ports; selecting All Ports Off (Dynamic) disables all
front and back USB ports during POST. Selecting All Ports Off disables all front and
back USB ports; selecting All Ports Off (Dynamic) disables all front and back USB
ports during POST. Selecting All Ports Off disables all front and back USB ports. The
default value is All Ports On.
When user accessible USB ports are set to All Ports Off (Dynamic), the Enable
Front Ports Only option is enabled.
Enable Front Ports Only enables or disables the front USB ports during the
operating system runtime.
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.
Enables or disables the internal USB port. This option is set to On or Off. The default
value is On.
The Internal USB port is on the PCIe riser 1b.
Internal USB port is only effective for T150, but T350/R350/R250 are not because
hardware does not support.
iDRAC manages the iDRAC Direct USB port exclusively with no host visibility. This
option is set to ON or OFF. When set to OFF, iDRAC does not detect any USB
devices that are installed in this managed port. The default value is On.
Enables or disables the I/O Acceleration Technology (I/OAT) option. I/OAT includes
DMA features designed to accelerate network traffic and lower CPU utilization. Enable
only if the hardware and software support the feature. The default value is Disabled.
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
