In my particular case, the only options I care about are IP, netmask, next-server, and possibly gateway which should all be present in the initial DHCP response used by the PXE ROM. I use the next-server field to find the config server to chainload a more detailed config script via HTTP (based on MAC address). Do I need to do anything special to make this work besides this? I'm using undionly.kpxe + an embedded script. set use-cached 1 dhcp net0 Thanks, Greg _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo/ipxe-devel
