[ipxe-devel] iPXE with netboot.me

Hello Paul
can you try

  dhcp net0
  kernel http://netboot.me
  imgstat

and then tell us the output of imgstat?

Here's what I think is happening:
If you load http://netboot.me the normal HTML code for the website is
returned. As far as I know netboot.me checks the name of the HTTP
client. If it is gPXE it returns a netboot.me version of
undionly.kpxe. Now iPXE doesn't identify itself as gPXE, but as iPXE,
so the normal HTML code you see in your browser is returned. iPXE
interprets this HTML text as a PXE NBP and tries to execute it(there
is no way to identify a PXE NBP, so it is assumed as last resort for
any unknown data).
Obviously this won't have the desired effect but will crash the machine.

This is something that should be fixed at the netboot.me side of things.

Thomas
