Michael, Thank you so much once gain for your incredibly prompt response.
The approach that we are taking for this solution is to develop a specific option ROM which does not implement the full DHCP protocol etc. This option rom "knows" how to communicate with this management host to download PXE images and to boot these servers using these images. Thats the need motivation to try this option out. Secondly, I just wanted to generally step through the whole code and not only the dhcp portion so that I familiarize myself with the different interactions before slimming it down to potentially only the portion that executes the stages to download the code and then in the backend will communicate with hosts that contact me for this image. Question: is the sequence that I followed at the gPXE prompt to bring up and configure the networking interface correct? Is there something else to this. I checked the network interface and it is pingable. Will try this again though.

This is not specified in the gPXE documentation. You want the ".lkrn.tmp" file. (An .iso image is built using the .lkrn binary.) > 2) I get the following output: > > <snip> Are you able to ping 10.44.4.3 from the machine running gdb? Also, since you say that you just recently started to play: are you aware that there is a substantial amount of built-in debug code that can be enabled without having to go to the effort of using gdb? For example, if you are having problems with DHCP, then make bin/ipxe.iso DEBUG=dhcp will show you debugging messages related to DHCP. You can find some description of debug builds at http://ipxe.org/download#debug_builds HTH, Michael _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo/ipxe-devel
