Table 15. Integrated Devices details (continued) Option Description utilization. Enable only if the hardware and software support the feature. This option is set to Disabled by default. 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 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. Current State of Embedded Video Controller OS Watchdog Timer Empty Slot Unhide Memory Mapped I/O above 4 GB Slot Disablement 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. 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. 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. 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. 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 will be available for control. Serial Communication To view the Serial Communication screen, power on the system, press F2, and click System Setup Main Menu > System BIOS > Serial Communication. NOTE: The serial port is optional for the PowerEdge R350 system. The Serial Communication option is applicable only if the serial COM port is installed in the system. Table 16. Serial Communication details Option Description Serial Communication Enables the serial communication options. Selects serial communication devices (Serial Device 1 and Serial Device 2) in BIOS. BIOS console redirection can also be enabled, and the port address can be specified. Serial Port Address Enables you to set the port address for serial devices. This option is set to Serial Device1=COM2, Serial Device 2=COM1 by default. Pre-operating system management applications 11
