I have two "devices" using IA32 UEFI firmware with 64-bit hardware. An Asus EeeBook X502TA and qemu-system-x86_64 with an IA32 TianoCore firmware. Neither of these will boot from snapshots/amd64/install58.fs.
Attempting to run bootia32.efi from the UEFI shell of the qemu system simply tells me "Command Error Status: Not Found". The EeeBook is deficient, and doesn't provide an UEFI shell, but I suspect it fails for the same reason.
