I decided to go for a usb boot instead. I copied the iso using dd and could locate my usb stick as usb0 through devalias
But none of the booting commands works for me in openfirmware
gives me "couldn't locate PARTITION can't open usb0/disk@1:2,\\yaboot"
just "can't open usb0/disk@1:1,\\yaboot"
also tried all the variations like
the only dir command that doesn't give me "can't open the dir device" is
output is just
