Integrated Devices details About this task The Integrated Devices screen details are explained as follows: Option 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; selecting All Ports Off (Dynamic) disables all front and back USB ports during POST and front ports can be enabled or disabled dynamically by an authorized user or authorized users without resetting the system. The USB keyboard and mouse 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. NOTE: The Internal SD Card Port on the PCIe riser is controlled by Internal USB Port. iDRAC Direct USB The iDRAC Direct USB port is managed by iDRAC exclusively with no host visibility. This option is set to ON or Port 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. Integrated Network Card 1 Enables or disables the integrated network card (NDC). When set to Disabled, the NDC is not available to the operating system (OS). This option is set to Enabled by default. NOTE: If set to Disabled (OS), the Integrated NICs might still be available for shared network access by iDRAC. I/OAT DMA Engine Embedded Video Controller 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 Internal SD Primary Card OS Watchdog Timer 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. 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. 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. 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. 58 Pre-operating system management applications
