The first (and only) thing I wanted to do with the debian image was to check, whether the board is ok and running (no case of warranty).

I managed to setup RNDIS and Ethernet over USB and could ifconfig an new usb0 to an appropiate address. Finally I found the password for that board and could login via ssh. O happy day!

Many distribution are too colorful ;) and to much "emulating ...hrrrmmmm.... known OSes" for me. I do like more these old school stuff...not so much OK/CANCEL decisions to confirm that I really want what I have confirmed, which is my will. Just:Do it! ... so in the worts case, my faults remain /my/ faults ;) Ok, I could log into the board in the meanwhile and it seems to work. Mission accomplished. Next will be to setup GENTOO for that board. By the way: It is really fascinating...when UNIX recognized the electrical light of the world, computers had a printer and a keyboard and were of the size of a greater room. And one could count the CPU cycles in realtime. PDP10/PDP11 and friends... Now...I login into a board of 5cm x 2.5cm size and I am nearly sure that it will be possible to run SIMH on it to emulate a PDP11/PDP10 and start one of the old UNIX system tapes... and with a little luck with 100% of the original speed. > If you are stuck on running gentoo on an arm 9, find a reference > implementation for embedded gentoo on an arm-9 and start there.
