First attempt for LinuxPPC on a MVME2400

[Simone Piccardi <Simone.Piccardi@fi.infn.it>]

As first thank to all people that helped me (but I think this is only
the beginning!).
The first step was to set the environment )PPC4bug> ENV) for booting
PReP using the options:
Network PReP-Boot Mode Enable = Y
and 
VME3PCI Master Master Enable = N

The second step was to set up a PC to provide the boot directory. I used
a Pentium with a RedHat 5.2, and copied all files from
ftp://vcorr1.iram.es/pub/linux-2.2/ to the /tftpboot directory on that
PC, and set up the tftpd daemon (inside inetd.conf).
i renamed the file zimage_initrd-2_2.1 as zimage.

The thirsd step was to setup the network on th MVME2400, we did:

The last step was the booting attempt:

I tried also to start the  zimage_nfsroot-2_2.1 image, obtainig a
similar result, that is right because I did not setup any root tree for
the NFS.

My first questiona is: the warning:
prep_init: WARNING: can't find an OpenPIC on what looks like a PowerPlus
board

is due to the new hawk chipset? And the message:
openpic.c:548: illegal irq 9 from c011d5d0,[c011c4bc],[[c012c36c]]

is due to this problem? And what I have to do?

Before starting to build a tree I would like to know if there will be
any chance to boot on it at this stage or not. I'm still tring to build
a cross compiler, and for the moment I cannot try to build another
kernel.

Do you have any suggestion? 


Thank you in advance
