Installing on a G3 powerbook via netboot/tftp

[James Vandenberg <james@vandenberg.dropbear.id.au>]

Hi,

I'm trying to install Debian on a G3 Laptop, New world type, the model
before the Pismo, I think.

I have bootp and tftp set up, giving the mac a file to use to startup
with, that all works.

Except, I can't find the right boot image for the debian installer. I've
seen mention of yaboot, but that seems to be after the machine is set
up.

Help?

James.
