That means, your nodes don't even get as far as booting the linux kernel, so can't be a driver issue. Most likely causes:
a) The DHCP server on the head-node doesn't run. b) The nodes are physically not connected to the cluster BOOT network on which the head-node's DHCP server listens to requests (maybe you have multiple networks wrongly attached).
