NetBSD/rs6000 (project page) is an effort to port the NetBSD operating system to MCA RS/6000 computers. The initial target is PowerPC for ease of porting, but POWER systems should be possible as well.
Tim Rightnor is the lead developer and also maintains ports for PReP and newer OpenFirmware machines. He wrote an interesting paper on doing kernel bringup on new platforms like this.

Subject: NetBSD ported to the IBM MCA RS/6000 model 7006

Date: 12/17/2007 13:25:33[Please direct followup discussion to firstname.lastname@example.org] I am proud to announce the port of NetBSD to the IBM RS/6000 class of MCA-based PowerPC machines. NetBSD is the first free Operating System to run on this class of machines. The port was made to an IBM 7006-41T, which is a 601-based machine with MCA. It has not yet been tested on any other machines, but most other MCA/PowerPC based machines should be supportable. This port does not yet run on the 7012-3xx class of machines, or any other machine that has a POWER, POWER-RSC, POWER2 or POWER2-SC CPU. POWER-class machines will require significant CPU code to be written. This port does not cover PReP-based IBM RS/6000 machines, for those, please see port-prep. For OpenFirmware based RS/6000 machines, please see port-ofppc. The following machines are likely to run this port, or run it with minimal effort: 7006-42T/W, 7011-250, 7007-N40, 7009-C10/C20 Additionally, it is probably possible to port this to the following machines, with changes to the bootloader: 7012-G30, 7013-570/580/J30, 7015-98B/R30/R40/R50. The port currently does not fully reach single user mode, as there is still no bus_dma backend to talk to the MCA cards. At this point it is capable of booting the kernel, and talking to the com ports to provide console services. I hope to fix the lack of bus_dma in the next few months. This port was made possible by Kevin Bowling, who provided both the hardware, as well as a pile of excellent books and documentation for the port. To build this port: check out recent CVS sources. cd to src ./build.sh -m rs6000 -T /usr/src/tools/ppc-hack -O /obj/rs6000 tools kernel=GENERIC cd sys/arch/rs6000/stand /usr/src/tools/ppc-hack/bin/nbmake-rs6000 cd mkbootimage make USETOOLS=NO /usr/src/hackathon/sys/arch/rs6000/stand/mkbootimage/mkbootimage -b /usr/src/hackathon/sys/arch/rs6000/stand/boot/boot -k /obj/rs6000/sys/arch/rs6000/compile/GENERIC/netbsd -s /tftpboot/rs6000.boot Create an entry in your bootptab or dhcpd.conf to boot the machine, set the keyswitch to service and hook up a serial console. Then you should be able to boot the image over the network.
