it tells you everything on that table. Not all fats are NANDS. All slims(regular) are NOR, but unless it was manufactured with 3.55 or lower, you cannot downgrade it.
You need a console that was manufactured with 3.55 or lower firmware, with a NAND or NOR chip, depending on what type of flasher you are trying to use.
I read it before looking at the table. Mine was manufactured with 2.16 or 2.30 and it's NOR.
