- 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.
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 or Off. 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.
- Embedded NIC1 and NIC2
-
Enables or disables the Embedded NIC1 and NIC2 options. If set to Disabled, the NIC may still be available for shared network access by the embedded management controller. The embedded NIC1 and NIC2 options are only available on systems that do not have Network Daughter Cards (NDCs). The Embedded NIC1 and NIC2 option is mutually exclusive with the Integrated Network Card 1 option. Configure the Embedded NIC1 and NIC2 option by using the NIC management utilities of the system.
- NOTE: The Embedded NIC1 and NIC2 options are only available on systems that do not have Integrated Network Card 1.
- 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.
- 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 will be used as the primary display. BIOS will output displays to both the primary add-in video and the embedded video during POST and pre-boot environment. The embedded video will then be disabled right before the operating system boots. This option is set to Enabled 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 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.
- SR-IOV Global Enable
- Enables or disables the BIOS configuration of Single Root I/O Virtualization (SR-IOV) devices. This option is set to Disabled by default.
- Internal MicroSD Card Port
- Enables or disables the internal SD card port of the Internal Dual SD Module (IDSDM). This option is set to On by default.
- Internal MicroSD Card Redundancy
- Configures the redundancy mode of the Internal Dual
SD Module (IDSDM). When set to
Mirror Mode,
data is written on both
SD cards. After failure of either card and replacement
of the failed card, the data of the active card is copied to the offline
card during the system boot.
When Internal SD Card Redundancy is set to Disabled, only the primary SD card is visible to the OS. This option is set to Disabled by default.
- Internal microSD Primary Card
- When Redundancy is set to Disabled, either one of the SD card can be selected to present itself as mass storage device by setting it to be primary card. By default primary SD card is selected to be SD Card 1. If MicroSD Card 1 is not present, then the controller will select MicroSD Card 2 to be the primary SD card.
- 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.
- Memory Mapped I/O above 4 GB
- Enables or disables the support for the PCIe devices that need large amounts of memory. Enable this option only for 64-bit operating systems. This option is set to Enabled by default.
- Memory Mapped I/O above Base
- When set to 12 TB, the system will map MMIO base to 12 TB. Enable this option for an OS that requires 44 bit PCIe addressing. When set to 512 GB, the system will map MMIO base to 512 GB, and reduce the maximum support for memory to less than 512 GB. Enable this option only for the 4 GPU DGMA issue. This option is set to 56 TB by default.
- Mezzanine Slot Disablement
- The Slot Disablement feature controls the configuration of mezzanine cards installed in the specified slots. Only mezzanine card slots that are present on your system are available for control.
