[Soekris] Installing Debian on the Net 5501

[Robin Kipp]

Hi all!
of course, I already tried installing Debian on my new Soekris box, by
setting up a TFTP and DHCP server as instructed on wiki.soekris.info.
However, when I typed "boot F0" in the ComBios, it always said something
like "media check failed, please check the cable"... The same result
came up when I set up a TFTP server under Debian Linux. Does anyone know
how to solve this problem? Am I maybe better off installing it from a
computer to the CF card directly? Thanks for help!!!
