Not sure about the next command:

dev /pci/pci10de,141 at 10 works as expected.

But, I’m not sure about the next command, should it be

: open true ; with a space between : and open, that returns "open is not unique". Maybe running up against the generic FCode that Openbios loads for all VGA devices, it already has the open word?

:open true; this returns :open: undefined word.

Thanks for the help, it’s been so many year since I fooled with Openfirmware that I’ve forgotten much of what I knew, whitch wasn’t that much to begin with. I always wanted to figure out how to test FCode Roms on cards before I flashed the EPRom, but I never did figure it out, so I just flashed each Rom to see if/how it would work.
