As many people have noticed, default yaboot install won't boot unless a screen is attached. Actually, the workaround is really simple. Thing is, that's the "ofboot.b" script that messes things up. This script is a "bridge", that actually either starts yaboot or let you boot off of a CD. I don't know what's the point, since OpenFirmware already lets you boot off of the CD by pressing C on boot=E2=80=A6 So basically, to boot headless, all you have to do is to tell OpenFirmware to boot straight off the yaboot binary, and to skip the ofboot.b Just boot into OpenFirmware (Command-Option-O-F), and type : setenv boot-device hd:2,yaboot (where 2 is the number of the partition containing yaboot) boot And here you go, you can unplug that useless monitor :-) References : http://saintaardvarkthecarpeted.com/blog/archive/2005/02/THE_WINE_OF_BOOT.h= tml http://grub.enbug.org/TestingOnPowerPC By the way, as of writing this, grub2 on PPC from debian gives a "out of memory" issue. Known bug.
