The architecture may be i386, but the assembler syntax can be either Intel
or AT&T (I haven't actually looked at the grub source code).  The gas
assembler uses AT&T syntax by default, most other assemblers use Intel.

At this point I will include a picture, because our search engine

more than 400 words without one.
