I would suggest using an embedded script. You can do this using make bin/ipxe.iso EMBEDDED_IMAGE=stjoe.ipxe where stjoe.ipxe is a text file containing: #!ipxe dhcp chain tftp://my-server1/my-filename || chain tftp://my-server2/my-filename || chain tftp://my-server3/my-filename || echo Boot failed exit 1 This will try each server in turn, falling through to the next entry in the list if it fails for any reason. Note the trailing "||", which is required to prevent the script from immediately aborting if the "chain" command fails. Note that this method will *not* set the "next-server" and "filename" variables. It is possible that your PXE NBP may require these variables to be set. If this is the case, you can use a slightly longer version of the above script: #!ipxe dhcp set filename my-filename set next-server my-server1 chain ${next-server}/${filename} || set next-server my-server2 chain ${next-server}/${filename} || set next-server my-server3 chain ${next-server}/${filename} || echo Boot failed exit 1 Michael Notice from St. Joseph Health System: Please note that the information contained in this message may be privileged and confidential and protected from disclosure. _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo/ipxe-devel
