@yeet If you look at the very top of that wiki page it actually explains all of the arch types.
Type Architecture Name ---- ----------------- 0 Intel x86PC 1 NEC/PC98 2 EFI Itanium 3 DEC Alpha 4 Arc x86 5 Intel Lean Client 6 EFI IA32 7 EFI BC (EFI Byte Code) 8 EFI Xscale 9 EFI x86-64Unless you think you might run across 1, 2, 3, 4, 5, 8 you probably won’t need to configure them. FOG Doesn’t have a iPXE boot loader anyway for those arch.
