Eric,

Below is all of the information Chuck provided me last time this issue
came up.  I have not had the chance to get this to work yet but you
could probably make more sense of this than myself.  The text below is
just a quick cut and paste somewhat in sequence of our emails.  I think
from it you should be able to extract the procedure.  In one reply to
Chuck I made an attempt at a procedure summary as you can see towards
the bottom. Thanks again for your efforts.

-----------------------------------------

Jim: i am netbooting four diff apples with openfirmware bases directly
yo ltsp..what it takes is the /opt/ltsp/ppc folder which is a tar file
billc created...and the contents of his tftpboot folder..plus a tweak in
dhcp to pass option 43.. i will switch machines and try to give you a
url if you are interested..chuck

<http://169.244.180.190:81/ltsp-ppc.tar.gz>
<http://169.244.180.190:81/apple.tar.gz>
this the nfs file system and contents of tftpboot plus i think a working
dhcpd.conf..chuck
i do cmd-option o f to go into openfirmware then at ok> prompt type boot
enet:192.168.0.1
once that works you can change startup disk to network and let er
rip..chuck

i just threw all my confs in when i got it working in philly..might need
a hosts reference to keep nfs happy..exports should be such that nfs can
export /opt/ltsp/whatever.. might need to check perms..i believe you can
use same box for i386 andd ppc..i used to with the nubus.. might want to
put that encapsulated stuff in a specific host in dhcpd.conf but i am
pretty sure i386 ignores it...best of luck..and lemme know how it comes
out..you might need to try a couple different video card designations in
lts.conf..bill-xc says some may need glx mopdule loaded...chuck
