OS X Leopard re-install / PPC G4 to PPC G5 in Firewire Target Mode ?

Hi ...

What is it, that I'm doing wrong here ; or missing out .

I got them 2 PPC:s connected to each other using a firewire cable (pretty obvious, isn't it) .

I see the (target machine) G5's internal HDD on the Desktop of the G4 and I have a Leopard install DVD in the G4's (source machine) drive .

But this is where I'm a bit lost ... There's this firewire icon (orange on blue) on the target machines display (yes, I booted with "T"), but won't get past this ...

So just a simple question, "what is there to do here on" ?
