[K12OSN] Booting macs

Thanks everyone for their help so far. I'm narrowing down the problem, and
I think I'm nearly there.
At first I wanted to make sure that the DHCP server was working properly for
the mac, so I changed the network card on the mac to take dhcp, which it did
with no problem, getting 192.168.0.211.
I went to the messages log, and saw something to the effect of "not
authoratative for the subnet 192.168.0.0" Somewhere in google, I saw that I
should add the line "authoratative;" (without quotes) to the top line of the
dhcpd.conf, which I did, then restarted dhcpd.
Now in my messages log, it looks like it gets the ip address, but never
gives out the OS.
For a successful boot with x86, it looks like:
Aug 26 09:31:15 ltsp dhcpd: DHCPDISCOVER from 00:10:4b:57:f2:68 via eth0
Aug 26 09:31:16 ltsp dhcpd: DHCPOFFER on 192.168.0.213 to 00:10:4b:57:f2:68
via eth0
Aug 26 09:31:16 ltsp dhcpd: DHCPREQUEST for 192.168.0.213 (192.168.0.254)
from 00:10:4b:57:f2:68 via eth0
Aug 26 09:31:16 ltsp dhcpd: DHCPACK on 192.168.0.213 to 00:10:4b:57:f2:68
via eth0
Aug 26 09:31:22 ltsp dhcpd: DHCPDISCOVER from 00:10:4b:57:f2:68 via eth0
Aug 26 09:31:22 ltsp dhcpd: DHCPOFFER on 192.168.0.213 to 00:10:4b:57:f2:68
via eth0
Aug 26 09:31:23 ltsp dhcpd: DHCPREQUEST for 192.168.0.213 (192.168.0.254)
from 00:10:4b:57:f2:68 via eth0
Aug 26 09:31:23 ltsp dhcpd: DHCPACK on 192.168.0.213 to 00:10:4b:57:f2:68
via eth0
Aug 26 09:31:23 ltsp rpc.mountd: authenticated mount request from
ws213.ltsp:657 for /opt/ltsp/i386 (/opt/ltsp/i386)
Before I added the authortative line, it looked like:
Aug 26 09:50:55 ltsp dhcpd: DHCPDISCOVER from 00:14:51:07:39:ba via eth0
Aug 26 09:50:56 ltsp dhcpd: DHCPOFFER on 192.168.0.216 to 00:14:51:07:39:ba
via eth0
Aug 26 09:50:56 ltsp dhcpd: DHCPREQUEST for 192.168.0.216 (192.168.0.254)
from 00:14:51:07:39:ba via eth0
Aug 26 09:50:56 ltsp dhcpd: DHCPACK on 192.168.0.216 to 00:14:51:07:39:ba
via eth0
Aug 26 09:51:00 ltsp dhcpd: DHCPINFORM from 192.168.0.216 via eth0: not
authoritative for subnet 192.168.0.0
Aug 26 09:51:58 ltsp last message repeated 3 times
After I added the authortative line:
Aug 26 12:51:35 ltsp dhcpd: DHCPDISCOVER from 00:0d:93:53:d8:ca via eth0
Aug 26 12:51:36 ltsp dhcpd: DHCPOFFER on 192.168.0.211 to 00:0d:93:53:d8:ca
via eth0
Aug 26 12:51:36 ltsp dhcpd: DHCPREQUEST for 192.168.0.211 (192.168.0.254)
from 00:0d:93:53:d8:ca via eth0
Aug 26 12:51:36 ltsp dhcpd: DHCPACK on 192.168.0.211 to 00:0d:93:53:d8:ca
via eth0
Aug 26 12:51:40 ltsp dhcpd: DHCPINFORM from 192.168.0.211 via eth0
Aug 26 12:51:40 ltsp dhcpd: DHCPACK to 192.168.0.211
Aug 26 12:51:49 ltsp dhcpd: DHCPINFORM from 192.168.0.211 via eth0
Aug 26 12:51:49 ltsp dhcpd: DHCPACK to 192.168.0.211
Aug 26 12:52:05 ltsp dhcpd: DHCPINFORM from 192.168.0.211 via eth0
Aug 26 12:52:05 ltsp dhcpd: DHCPACK to 192.168.0.211
Aug 26 12:52:38 ltsp dhcpd: DHCPINFORM from 192.168.0.211 via eth0
Aug 26 12:52:38 ltsp dhcpd: DHCPACK to 192.168.0.211
Like it's just cranking away, but not getting that kernel. I do have
/opt/ltsp/ppc/etc/lts.conf file that has been mentioned.
Any clues as to where to look?

The flashing tile with the globe means it's trying to netboot. When it is
working correctly on my one Mac (sheesh, give the guy a Mac and suddenly
he's an authority on it
;-)) the tile blinks only once or twice, and then starts booting from the
server.
Initially, it wasn't working for me, with the tile blinking for several
minutes, just like yours, because I don't use the default 192.168.0.x
addressing, but the ppc lts file does. When I changed the addressing in the
ppc lts.conf file, it started working. So, lots of words to say that it
sounds like your Mac isn't finding the server.
To answer your last question, yes, you can have your server booting both x86
and ppc clients at the same time. I love showing that off to people,
demonstrating how flexible Linux is.
