Load a 64-bit EFI Image from 32-bit EFI bootloader - ChrisLucas29 - 2018-10-23 14:33

Hello,

I'm trying to load a 64-bit Image from 32-bit bootloader. I know that on Ubuntu there is a work around (here).
I was wondering if it was possible through IPXE.

EFI iPXE calls firmware functions to load the next EFI binary.
As such you will have to get implementations of those functions to accept the "wrong-bit" binary, (which AFAIK does not exist)
This is unlikely to be implemented in iPXE if at all possible, partly because it is "rare" and partially because it would have security implications which would limit the possibility to have iPXE signed.
