@Tom-Elliott @Wayne-Workman I solved my problem with a workaround.
Using my iPXE cd that doesn’t have param, I booted to the ipxe.pxe provided with fog.
From there I was able to boot default.ipxe.
TL;DR
Boot CD.
chain tftp://myip/ipxe.pxe
shoots some error.
I press s to go to command line.
param
returns nothing.
chain tftp://myipdefault.ipxe
Text flies by, and the computer begins to create an image!
Thanks for the help!
