What happened before - linux is on it's way

The T1000 automagically boots into Solaris10 setup. So I answered all the annoying questions, using the dead slow 9600 bps serial over telnet connection. "uadmin 2 0" makes an end to this. So we should be on Open Boot Prompt "{0} ok" right now.
Time to deactivate Solaris autoboot: "setenv autoboot? false".

For booting linux I chose the ubuntu bootable network image.

In order to boot T1000 via network you have to prepare two things: a rarp server and a tftp server. No problem, debian delivers it all via apt-get, package names are "tftpd" and "rarpd".

To configure rarpd you have to create/expand a file "/etc/ethers". There you simply put a line containing mac adress of eth0/bge0 of your T1000 (can be found on the neon orange customer information sheet) and desired ip-adress for it. Then simply "/etc/init.d/rarpd start" and rarpd is up and running.

To setup tftpd you should check that the tftp-line in "/etc/inetd.conf" is not commented out. All files that should be served have to be in "/tftpboot" dir. So we put our bootable network image there. After that there has to be a symbolic link to this file. The link name is the ip address of the T1000 coded in hex uppercase letters. For example 192.168.1.1 translates to C0A80101. "ln -s boot.img C0A80101" should do the trick.
