Embedded Video
Controller 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 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 .

When Internal SD Card Redundancy is set to
Disabled , only the primary MicroSD card is visible to the OS. This
option is set to Disabled by default.
