Datapath VSN890 - Manual (Page 9)

Use of the SBC’s onboard graphics adaptor
Onboard Graphics Adaptor used as Control Screen
The VSN890 is shipped with the BIOS configured to boot off the onboard graphics device. This output can
then be used as the control screen for a typical wall configuration.
To set the system to boot on the onboard graphics device (“Internal Graphics Device” - IGD), enter setup
from the boot screen by pressing as prompted.
In the BIOS setup utility select:
Boot>Primary Display>OnBoard VGA
CAUTION: If the SBC BIOS is setup for IGD as above, then you must not insert an Image4 or other
VGA graphics card in the first (x8 lane) PCIe slot (Fig.7).
Please note that when the VSN890 is configured with a Vision800X expansion chassis, the first slot of the
host machine is taken up by the H-Link card, so the above prohibition refers to the first slot of the
expansion chassis.

The system will then boot on the primary screen of the bottom connector of the graphics card that is
closest to the SBC, irrespective of the settings of the identification links on the Image4 graphics cards. In
this context “closest to the SBC” is defined in terms of the PCI bus enumeration, so if a Vision800X is
attached to the host, the system will boot on the first VGA card to be discovered in the Vision800X
(counting from the slot closest to the S-Link slot), and failing that the first graphics card in the host
machine.
When the BIOS is set to PEG/PCI as above you are free to install the Image4 cards in any PCIe slot,
including the first (x8 lane) slot.
