SGI: Video

I keep forgetting to ask this, but...

...How does one run Cosmo2 (in an Octane) without any gfx? Is it even possible? I've tried to run dmplay, and all I get is an alphabet soup of &c. errors whenever I leave out the SI board.

(Trying to run it without gfx reduces the noise and heat output, and makes using Pachyrhinosaurus as a really energy inefficient DVR more feasible in the living room).

EDIT: I should have said dmplay is set to put video out on Cosmo2, not gfx.
