hey Rioch!!
I tryed it too, documentation about FTP install:
README.FTP
conclusion:
make a boot CD, then install directly from ftp by intering:
linux install=ftp://[IP-ADRES]/pub/suse/i386/9.0
(dependant on youre choice for a mirror!)
But the, a installation programme starts. There i encounter a problem.
Because my setup can't find the needed packages. So don't I. So i'm afraid the ftp install is not yet complete...
grtz.!
