[K12OSN] K12LTSP FC5 server + Edubuntu 6.06.1 LTS server = No boot

[Mella]

Hello!

I'm trying put together FC5 and Edubuntu but no success.
Separately, if server is only DHCP server in network, all seems OK. IBM 
T21 client boot to Edubuntu perfectly.
If I shut down this dhcp service and add specific workstation section to 
FC5 server's dhcp conf, client stops in the mid of boot.

I see graphical Edubuntu bootup, then "configuring LTSP", then come 
messages (see below) an after that i see blank screen with cursor in 
upper left corner. And that's it.

If I try put together 2xFC5 servers with one DHCP server, all working OK.

I don't have ideas how continue.

dhcp ws section in FC server:

    host ws192 {
        next-server      192.168.1.13; # Edubuntu server ip
        hardware ethernet     00:03:47:0f:cc:9f;
        fixed-address         192.168.1.192;
  filename "/ltsp/pxelinux.0";
  option root-path "/opt/ltsp/i386";

    }
