Not really. I got NetBSD/ofppc 1.6 with the generic OpenFirmWare
drivers to the point where it wants to start the single user shell,
but /bin/sh crashed. (Maybe due to my setup.)
port-prep will not run on the PowerStack II. port-prep needs the
residual data, but the firmware of the PowerStack II doesn't provide
I am working on a "real" port of NetBSD/ofppc to this machine with
PCI bus support etc. etc. etc. I have a working PCI bus attachment
and I am currently working on the ISA attachment. But this needs
some work on the machine dependent bus_space(9) infrastructure in
port-offppc. As I havn't done this bevore my progress is somewhat
slow, but there is progress.
(Many thanks to Ignatios for some enlightenment on bus_space(9))
If you wane help: I have no clue about the interrupt routing and
interrupt controller in this machine. It may be possible to get
this information by reverse engineering the Linux source.
You are welcome to do this obnoxious work for us. ;-)
