Description
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 SD card port. This option is set to On or Off.
This option is set to On by default.
NOTE:
The Internal SD Card Port on the PCIe riser is controlled by Internal
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.
Enables or disables the integrated network card. When this option is set to
Enabled, the card is not available to the operating system. This option is set to
On by default.
NOTE:
If set to Disabled (operating system), the Integrated NICs might
still be available for shared network access by iDRAC.
Enables or disables the Embedded NIC1. If set to
Disabled (OS), the NIC may still be available for shared network access by the
embedded management controller. Configure the
Embedded NIC1 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 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.
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.
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 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 Enabled.
Enables or disables the BIOS configuration of Single Root I/O Virtualization
(SR-IOV) devices. This option is set to Disabled by default.
