Hello Chris,

thanks very much, it worked perfectly with dump and restore, then chrooting 
to /mnt/working
and doing a  /sbin/silo -f -C /boot/silo.conf.
What took me some time was, that ftp could not transfer the dump file, that 
had a size of around 2.3G. I had to split that to smaller pieces first. I 
was not aware of the fact that there is a size limitation in ftp... And 
also the "restore" binary is not on the install CD, but its no problem to 
copy that from the existing system.

Best regards,

Christoph
