3.3.1.2Video Memory Interface

The memory controller sub-system of the ES1000 arbitrates requests from the direct memory interface, the VGA graphics controller, the drawing co-processor, the display controller, the video scalar, and the hardware cursor. Requests are serviced in a manner that ensures display integrity and maximum CPU/co-processor drawing performance.

The server board supports a 16MB (4Meg x 16-bit x 4 banks) DDR SDRAM device for video memory.

3.3.1.3Dual Video

The BIOS supports single and dual video modes. The dual video mode is enabled by default.

•In single mode (Dual Monitor Video = Disabled), the on-board video controller is disabled when an add-in video card is detected.

•In dual mode (On-board Video = Enabled, Dual Monitor Video = Enabled), the on-board video controller is enabled and will be the primary video device. The external video card will be allocated resources and is considered the secondary video device. BIOS Setup provides user options to configure the feature as follows.

On-board Video	Enabled
	Disabled
Dual Monitor Video	Enabled	Shaded if on-board video is set to "Disabled"
	Disabled
