Option Integrated RAID Controller Embedded NIC1 and NIC2 I/OAT DMA Engine Embedded Video Controller Description Enables or disables the integrated RAID controller. This option is set to Enabled by default. NOTE: The Embedded NIC1 and NIC2 options are only available on systems that do not have Integrated Network Card 1. 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. 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 is used as 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 pre-boot environment. The embedded video is disabled 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 re-arrange the cards in the slots in order to control which card is the primary video. Current State of Embedded Video Controller SR-IOV Global Enable Internal SD Card Port Internal SD Card Redundancy 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. Enables or disables the BIOS configuration of Single Root I/O Virtualization (SR-IOV) devices. This option is set to Disabled by default. Enables or disables the internal SD card port of the Internal Dual SD Module (IDSDM). This option is set to On by default. 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 SD Primary Card By default, the primary SD card is selected to be SD Card 1. If SD Card 1 is not present, then the controller selects SD 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. Empty Slot Unhide Enables or disables the root ports of all the empty slots that are accessible to the BIOS and OS. This option is set to Disabled by default. Memory Mapped Enables or disables the support for the PCIe devices that need large amounts of memory. Enable this option only I/O above 4 GB for 64-bit operating systems. This option is set to Enabled by default. Memory Mapped I/O Base When set to 12 TB, the system maps the MMIO base to 12 TB. Enable this option for an OS that requires 44 bit PCIe addressing. When set to 512 GB, the system maps the MMIO base to 512 GB, and reduces 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. Slot Disablement Enables or 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 are available for control. 46 Pre-operating system management applications
