Description
embedded management controller. Configure the Embedded NIC1 and NIC2
option by using the NIC management utilities of the system.
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.
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.
Sets the LCLK frequency for Bus address 0x00.
Sets the LCLK frequency for Bus address 0x20.
Sets the LCLK frequency for Bus address 0x40.
Sets the LCLK frequency for Bus address 0x60.
Sets the LCLK frequency for Bus address 0x80.
Sets the LCLK frequency for Bus address 0xA0.
Sets the LCLK frequency for Bus address 0xC0.
Sets the LCLK frequency for Bus address 0xE0.
When set to Enabled, you can provide the Bus address (in decimal) to choose
end device for preferred IO Bus. This option is set to Disabled by default.
When set to Enabled, the LCLK speed for the root complex where Preferred
IO is enabled will automatically be set to 600 MHz (effective 593 MHz).
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 Mirror 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. This
option is set to SD Card 1 by default.
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
