Boot variables is the app you need. It will let you set the input and 
output devices that OF uses to communicate with you. On your J700 you 
should set your input-device to kbd and your output device to your video 
cards OF name. The 4MB twin turbo in my machine is seen as 
/bandit/imstt128m the 8MB card is seen as /bandit/imstt128mb8 and if 
they are in the lower slots you must add /pci-bridge/ between bandit and 
the video card identifier(I don't know if this applies to the J700 - how 
many PCI slots?). If your matrox card supports OF, you should be able to 
use it.

Regardless, the netbsd web site has a much more thorough explanation of 
OF on their web site - http:/www.netbsd.org. You can also use the apple 
utility mentioned there - System Disk - to change the Open Firmware 
variables. Check out the above website under the macppc port - lots of 
good info. This old s900 boots linux, NetBSD, and MacOS 9.2.2 from OF 
and bootstraps off of MacOS 7.5.5 to run BeOS 4.5 :)

ps - I want a pegasos machine when the dual g4 option is available 
(either that or an old SGI)
