Right, but curently I am using arm/i386 packages unpack it, delete all
stuff not needed and repack it... (most is working directly without
intervention of my part from a script I have written)
I want to put an 480x256dor matrix 64color display on my Computer and
have the need for many software which I do not realy like to code my
own.
It is already enough, If I have to read the xsepcs to get an xserver
runing... I do not find if realy funny to code a xserver, but I need
one so I must code one (but it will only support the absolut minimal
functions of X)
However, I run many software on it and the FULL installation would be
around 400 Debian packages

I have had to install a little ASM routine into the ROM of the LH7
and now it know HOW to load the BSD image, but it does not work for
Linux maybe the CF-Card IS already working (and I do not know it,
since the bootloader is not working with it...)

I had problems with that... And I have put it here:
<http://freenet-homepage.de/linux4michelle/electronica/files.jpg>
Note: The Image is already outdated because since today
(Saturday 2007-03-08) I have 3 files and 1020 pages
more documentation including 800 pages about TINI-OS
(I need to get "sdcc" running)
And of course, I need to find the section of the bootloader for the ARM
and HOW to code my own one...

I do not know, whether it is enough... Maybe I should use an ARM11?
And of cources I am working on energy eating electronic...
(In general sensors of any kind... but I have already found more
modern µChips which are consuming only 2-5% of the old ones...)

I know some peoples with problems to install Debian on it, so I have
choosen not to reinstall it and waste my time anywhere... :-/

Oh, I am not THE genious one, but I can say: "It works for me!"; and
since most of my Electronic I build are embedded systems without
Internet connection or something like this, I can say, it is working
"very" secure.

AFAIK, the guy who has written the 1-Wire temperature sensor module has
written in the source, that someone can use this source as template to
code stuff for other 1-Wire modules... :-)

Right, and in the Datasheets/AppNotes of Maxim there are many examples
how to do it (and even Linux is mentioned)
