Ultra 10 Creator 3D: enabling onboard VGA

Hello,

I have an Ultra 10 Creator 3D working fine with a Sun monitor, but I'd like to use it with a VGA flat panel (it would be great if I could use both screens simultaneously).

As I've read in a previous thread (http://www.unix.com/sun-solaris/14875-creator-3d-video-adapter.html\) this box as an on board VGA adapter. When I plug into it a VGA screen nothing comes out there. Is there a way to enable/disable such an on board VGA adapter? Maybe mine is disable and needs enabling?

Ideas, please?

Nothing much to set. As long as your OBP points to screen for output-device and you bootup, you should see the display
