Booting on a 32 bits EFI shows up a 32 bits missing kernel architecture Tried out various configurations, diffrent GPU, nothing shows up on display, freeze

Though the debugger message explains it, I don't understand ATM why it cannot load OpenCore.efi . Is that 32 bits EFI of the card's missing too ?

Need DEBUG kernel to be sure, but in general 32-bit OpenCore can only load 32-bit kernel.

Alright sorry PSU failed one month ago.. I see clearly that I was trying to start the mac (10.11) from opencore on a MP 2,1 equipped with the Kepler GPU arch But the K32 x86 kernel was removed in 10.8 already.. that's what's in trouble

Nb : I ended up in El Capitan with the mac firmware without bootscreen , I had to enable autologon after hacking the NVIDIA web drivers and disconnected the original ATI dvi port.

cc @mikebeaton, @Goldfish64, maybe we can consider booting 64-bit OS on 32-bit EFI with OpenCore?
