Memory Configuration - Foxconn A85GM Series User Manual

concept, wherein a static amount of page-locked graphics memory is allocated during driver
initialization. This fixed amount of memory will provide the user with a guaranteed graphics
memory at all times, and will no longer be available to the OS.
► Primary Video Controller
This item is used to select which graphics controller is used as the primary boot device.
► Surround View
Surround View is the ATI technology that provides multi-graphics controller display capability
for both the ATI PCIe-based graphics card and the ATI integrated graphics processor (IGP).
Enabling SurroundView does not impact display modes (resolution and color depth) or perfor-
mance. The display mode of each output is controlled independently by the graphics controller
connected to it.
1. When using a non-ATI PCI Express (PCIe) graphics card, Surround View is not supported.
The integrated graphics processor (IGP) is automatically disabled, and the system memory
allocated to the IGP is freed for other use.
2. PCIe graphics card is the default first display device. Enabling SurroundView in the BIOS
enables the integrated UMA graphics controller, which in turn makes available up to two
additional graphics outputs. When enabling the integrated UMA graphics controller, system
memory will be reallocated.
► AMD 880 HD Audio
This item is used to set whether the HD Audio controller is enabled through the HDMI port on
the rear panel.
