Are there changes to this? I tried to enable different images types including bzImage, but make fails on me. See this for details if interested - https://gist.github.com/korekhov/9435796...0ce7b4e0ba

The issue I'm trying to get past is this error I get when loading CentOS7 vmlinuz/initrd:

Am I even correct to think that my ipxe.efi is missing proper image support?
Thanks!
