I have run quik on my Linux partition and using some examples i found in the
FAQ-O-MATIC i set my boot variables (i don't have them infront of me but this
is as close as i can remember):
boot-device /pci@80000000/Apple83C875Card@d/sd@0:0
boot-file /boot/vmlinux-2.2.14 video=atyfb:vmode:15,cmode:16,mclk:71
This gives me the claim failed error. Have i done this correctly and just
need to apply the patches that come with the SystemDisk app? or have i done
something wrong?
I will down load the SystemDisk app.. it is the one in the
ftp.apple.com/developer/macosxserver/utilites/ dir right?

"O God of Earth and Altar,
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
But take away our pride."
-G.K.Chesterton: English Hymnal
