Dell EMC PowerEdge R7425 Installation and Service Manual
Integrated Devices details
About this task
- 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) All Ports On disables all front and back USB ports during POST and front ports can be enabled or disabled dynamically by authorized users without resetting the system
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.
- Integrated Network Card 1
- Enables or disables the integrated Network Daughter Card (NDC). When set to Disabled (OS) , the NDC is not available to the operating system (OS). This option is set to Enabled 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 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. 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
- 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.
- 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 Limit
- Controls where MMIO is mapped. The 1 TB option is designed for specific OS which cannot support MMIO over 1 TB. This option is set to 8 TB by default. The default option is the maximum address that the system supports and recommended in most cases.
- 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 will be available for control.
Table 1. Slot DisablementThe table describes available PCIe slots on your system. Option Description Slot 1 Enables or disables or only the boot driver is disabled for the PCIe slot 1. This option is set to Enabled by default.
Slot 2 Enables or disables or only the boot driver is disabled for the PCIe slot 2. This option is set to Enabled by default.
Slot 3 Enables or disables or only the boot driver is disabled for the PCIe slot 3. This option is set to Enabled by default.
Slot 4 Enables or disables or only the boot driver is disabled for the PCIe slot 4. This option is set to Enabled by default.
Slot 5 Enables or disables or only the boot driver is disabled for the PCIe slot 5. This option is set to Enabled by default.
Slot 6 Enables or disables or only the boot driver is disabled for the PCIe slot 6. This option is set to Enabled by default.
Slot 7 Enables or disables or only the boot driver is disabled for the PCIe slot 7. This option is set to Enabled by default.
Slot 8 Enables or disables or only the boot driver is disabled for the PCIe slot 8. This option is set to Enabled by default.
- Slot Bifurcation
- Auto Discovery Bifurcation Settings allows Platform Default Bifurcation and Manual bifurcation Control.
The default is set to Platform Default Bifurcation. The slot bifurcation field is accessible when set to Manual bifurcation Control and is grayed out when set to Platform Default Bifurcation.
Table 2. Slot BifurcationThe table describes slot bifurcation details of your system. Option Description Slot 1 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation Slot 2 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation Slot 3 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation Slot 4 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation Slot 5 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation Slot 6 Bifurcation X8 or X4 or X4X4 Bifurcation Slot 7 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation Slot 8 Bifurcation X16 or X8 or X4 or X4X4X8 or X8X4X4 Bifurcation
