Etherboot on Ubuntu LTSP

[Jonathan Carter]

Hi

I'm trying to make etherboot (without PXE emulation) to work in Edubuntu.

I've replaced in dhcpd.conf:

"""
filename "/ltsp/pxelinux.0";
"""

with

"""
# trick from Peter Rundle <peter.rundle at au.interpath.net>, borrowed from
K12LTSP
if substring (option vendor-class-identifier, 0, 9) = "PXEClient"
{
  filename "/ltsp/pxelinux.0";
}
else
{
  filename "/ltsp/vmlinuz";
}
"""

When the etherboot thin client boots, it says that the kernel is an
invalid image. When I copy the K12LTSP vmlinuz.ltsp to /var/lib/tftpboot
and change the kernel name to vmlinuz.ltsp in dhcpd.conf, it loads the
kernel fine.

Any ideas on what could be different between the ubuntu kernel and the
LTSP.org kernel that could cause the one to work and the other not?
