Description
Controller is automatically used as the primary display even if the Embedded
Video Controller setting is Disabled.
Displays the current state of the Embedded Video Controller. Current State
of Embedded Video Controller is a read only field, indicating the current
state for the Embedded Video Controller.
Enables or disables the BIOS configuration of Single Root I/O Virtualization
(SR-IOV) devices. By default, the SR-IOV Global Enable option is set to
Disabled.
If your system stops responding, this watchdog timer aids in the recovery of
your OS. When this field is set to Enabled, the OS is allowed to initialize the
timer. When the option is set to Disabled (the default), the timer will have no
effect on the system.
Enables or disables the support for PCIe devices that require large amounts of
memory. By default, the option is set to Enabled.
Enables or disables the available PCIe slots on your system. The Slot
Disablement feature controls the configuration of PCIe cards installed in the
specified slot. Slot disablement must be used only when the installed
peripheral card is preventing booting in to the OS or causing delays in system
startup. If the slot is disabled, both the Option ROM and UEFI driver are
disabled.
Description
Selects serial communication devices (Serial Device 1 and Serial Device 2)
in the BIOS. BIOS console redirection can also be enabled and the port
address can be specified. By default, Serial Communication option is set
to Auto.
Enables you to set the port address for serial devices. By default, the
Serial Port Address option is set to Serial Device 1=COM2, Serial Device
2=COM1
NOTE: You can use only Serial Device 2 for the Serial Over LAN
(SOL) feature. To use console redirection by SOL, configure the
same port address for console redirection and the serial device.
NOTE: Every time the system boots, the BIOS syncs the serial MUX
setting saved in iDRAC. The serial MUX setting can independently be
changed in iDRAC. Therefore, loading the BIOS default settings from
within the BIOS setup utility may not always revert this setting to the
default setting of Serial Device 1.
You can associate the External Serial Connector to Serial Device 1, Serial
Device 2, or the Remote Access Device using this field.
