PXE is a DHCP mutant...

I have no more sharp details on PXE stuff.
It was a ugly tour to get it working, but it was achievable.

With PXE 2.0  I had better results as with PXE 1.1
( did spend a lot of time on 1.1 without the desired goal,
 got a PXE 2.0 working on the first encounter
 went back to 1.1 and managed to tune it the right way )

All was done begin 2001 with a self compiled PXE server.

What I have read from mailinglists is that the ISC DHCP server version 3.0
now has PXE support.

Tell us more about your DHCP configuration
and what you see with tcpdump and such a like tools.
