Option Description
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 Enabled.

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 support for the PCIe devices that require large amount of memory. Enable this
option only for 64-bit operating systems. This option is set to Enabled by default.
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,the Option ROM drivers are disabled. Only slots that are present on the system will be
available for control.
● Slot 1 — Enables or disables 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
