Thanks Keith and Ralf for your information on running a R10000 O2 with
Linux. I knew that the video and sound HW as well as some of the
machine's graphics features were not supported by any linux drivers,
because it's even hard on SGI/Irix to find useful documentation about
this hardware! I guess this is the point why so few developers have
programmed applications that would take advantage of the very nice
capabilities of the machine.
So, I still would like to contribute something to the implementation of
Linux on SGI machines and I have this O2 standing on my desk. I have
installed and maintained some I386 based linux systems, but am not
really into fixing kernels. As I see there's no kernel that will boot
rightaway (with or without screen console). Let me know if the situation
is hopeless or if I can make a step taking a current mips-kernel (any
specific R10000-patch around there?) and start to consult R10000/ SGI O2
It would be nice, but maybe I'm too much on the admin/user side and for
sure I am not into developing kernels. Anyway, curious I am...
