If that's a GPX or other uVax with video cards installed,
you may not get any console output with the graphics cards
plugged in, as fwir, console io gets redirected to graphics
if it finds any.

Best way is to bring it up bit by bit. Unplug the first
card past the cpu and memory, which will break bus grant,
then try again...
