- This is Linux's home port. Linux was originally native to the Intel
- 386, and runs on all the later x86 processors including the Intel
- 486, 586, Pentiums, and various instruction-set-compatible chips by
- AMD, Cyrix, and others.

- Port to the x86-64 architecture. x86-64 is a 64-bit extension to the
- classical 32-bit x86 architecture. For details see
