Video
The BIOS supports both single-video and dual-video modes. The dual-video mode is disabled
by default.
In the single mode (dual monitor video = disabled), the on-board video controller is
disabled when an add-in video card is detected.
In single mode, the onboard video controller is disabled when an add-in video card is
detected.
In dual mode, the onboard video controller is enabled and is the primary video device.
The external video card is allocated resources and is considered the secondary video
device.
When KVM is enabled in iBMC FW, dual video is enabled.
