@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 x86-64
Unless 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.
