3.5.2 Video Memory Interface
The memory controller subsystem of the ATI* 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.
3.5.3 Dual Video
The BIOS supports single and dual video modes. The dual video mode is enabled 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 the dual mode (On-board Video = Enabled, Dual Monitor Video = Enabled), the on-board
video controller is enabled and is the primary video device. The external video card is allocated
resources and is considered the secondary video device. The BIOS setup provides user options
to configure the feature as follows:
