[coreboot] iPXE as payload?

[Gert Menke]

Hi,

I would like to use iPXE as a secondary payload (rather than as option 
rom).
The advantage would be that iPXE would not need to be loaded on every 
boot, but I could still choose it in the SeaBIOS boot menu when I want 
to use it. Is this possible? If so, how?

Thanks
Gert
