Hi Gavin, I was just doing that when you responded. Here is dhcp.conf

authoritative;

subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.20 192.168.0.250;
  option domain-name "example.com";
  option domain-name-servers 192.168.0.1;
  option broadcast-address 192.168.0.255;
  option routers 192.168.0.1;
  option subnet-mask 255.255.255.0;
  if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
    filename "/ltsp/i386/pxelinux.0";
  }
  else{
    filename "/ltsp/i386/nbi.img";
  }
  option root-path "/opt/ltsp/i386";
}

After doing a search, I cannot find " /ltsp/i386/pxelinux.0" or
"/ltsp/i386/nbi.img" niether can I find the path "/opt/ltsp/i386"

There is a "/opt/ltsp/amd64" there is a /var/lib/tftpboot/ltsp/amd64 that
contains pxelinux.0 but no nbi.img I am going to change dhcp.conf to point
to /var/lib/tftpboot/ltsp/amd64/pxelinux.0 and the root path to
/opt/ltsp/amd64. I am not sure about /ltsp/i386/nbi.img as there is no
nbi.img

Regards,

Paul
