R: RS/6000 PPC 604e, 43P 140

I am working on the problem as well... and I think I can give you a couple
of answers...

Thanks to many "contributots" (especially Martin) I tried 10s of kernel
images on my Rs/6000 43P model 140.

The machine always hangs, but I don't think it actually crashes when
initalizing the console.   Infact, supposing problems with the video card I
removed it and worked on the serial console.  I can see on it "Linux PPC
loading, uncompressing the kernel..." and other usual stuff.  So the console
is ok.  What happens is after "Uncompressing Linux kernel... Now booting the
kernel" . I suppose that this is the time the kernel is trying to recognize
the processor type, the mother board bus, etc. etc.

The problem is not related to the floppy driver, I tryed to boot via BootP
and I got the same results, so I'm not going to remove the Scsi HD, buy a
IDE controller, etc. etc. : I'm not expecting much more than from the BootP

The SCSI card is supported, to find out what it is just look at numbers on
the chip, it should be a NCRxxx.
The machine is PreP and the hardware shuold all be supported, Philip said
IBM is working at the support (http://www.ibm.com/linux) ...

With BootP you just set a bootp server that according to the ethernet card
hw serial number answer to queries indicating the tftp server to use and the
name of the kernel file to download . You can also set other infos like the
client IP and netmask, the DNS, the domain, etc. etc.  No need to all that
stuff, just put the kernel file bigger than 1.44M in a directory of a linux
server and set a couple of files (/etc/inetd.conf and /etc/bootptab).  The
rs/6000 management will allow you to indicate the bootp server to use and
the initial ip of the client.  Then it works fine...  So there is no need to
have a bootable CD...
But we haven't a working kernel image... :-)


P.S.: I think that this should be the current situation for rs/6000 43P 140,
if anyone has different informations, please let me know (jacopo@silva.net).
If anyone has a rs/6000 43P 140 with a working kernel please let me know!!!
Thanks to all who sent me, or even compiled just for me, the kernel images I
tried until now.
