Changing iPXE signature - keithtobin - 2014-07-23 13:39

I have the following issue, I am booting a KVM VM (This may also be a server with BIOS pxe) and want to preform a iPXE boot. The problem I am having is detecting and exiting to chain as both have the iPXE signature, the KVM (iPXE) and the iPXE i load.

As I will be using this on hardware and VM I want a way to change the signature of the iPXE i load to somethig like 'iKT3' so I can detect it and pass it a script using DHCP and have it complet the boot sequence.

How could I change the signature in the code or is there a betetr way to do this?

You need to use something like the recipe I have on https://gist.github.com/robinsmidsrod/4008017 to make sure you get an iPXE environment with the features you need. The iPXE you have in "ROM" is a cut-down version that is not quite as feature-full as you need it to be.
