dnsmasq incompatibility?

[robinsmidsrod]

I would suggest you use the most recent build, which you can also build using http://rom-o-matic.eu/ and use DEBUG=autoboot, maybe this will shed some light on what's going on. Obviously you should just boot into iPXE using the normal chainloading, run dhcp followed by config and verify that the next-server and filename params are there. If they are not, then you need to look more carefully at your dnsmasq configuration.
