Booooooooooooooooting!

Hi All!

We've just reached a new milestone in the h2200 port to Linux.
Now the Penguin starts to boot and reaches it's first Kernel panic!

Special thanks to Joris who gave us more information about the booting
process. The "Error: a" message was caused by the bootloader (HaRET) not
sending the right architecture information. By adding "set MTYPE 341" to
the startup.txt file, we got rid of this error.

It's the best Kernel panic I have ever experienced!

See http://http://michaelo.free.fr/pda/h2210/HaRET/ to have the same
experience (just leave me a few minutes to update the files and write a
README file).

Now, we need a root filesystem! I will try to build a initrd file with
at least busybox for arm, hoping to run an interactive shell in the next
days or weeks.

Thanks of course to all the contributors who gathered or released specs,
wrote first kernel code, shared their ideas on the list and on the Wiki,
wrote tools like HaRET and make this project so nice to be part of!

:-)

    Michael.
