Description
POST. You 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 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.
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.
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.
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 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 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.
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.
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.
Enables or disables the BIOS configuration of Single Root I/O Virtualization (SR-IOV)
devices. This option is set to Disabled by default.
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.
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.
