Hi,

I've installed NetBSD on a 9500/120 via serial console but I want to set up 
output to monitor.

So, I changed output-device in OF, but when I turn on the machine, the monitor 
light becomes green but all I can see is a gray screen.

Booting via serial console, I can see this message:

---------------------
(...)

ofb0 at pci0 dev 13 function 0: cannot map framebuffer

(...)
---------------------

What's wrong?

Thank you.
