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/mkbooti

/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. (the above paths are just
examples, edit for
your environment)
