After half a weekend at LinuxForum 2006 I retuned with a Soekris Engineering net4801 witch I got from Wim Vandeputte, who runs KD85.com.
Now the challange was: How to install something on it. The solution was at Ultradesic site. They got a very through HOWTO on how to install most *BSDs (FreeBSD, OpenBSD, NetBSD and miniBSD) and some Linux distros on this SBC.
Worth checking out if you either have a Soekris 4801 or are considering to get one.
