- Well, not exactly. There are some non-protected mode instructions provided
- by the 80286 that are not part of the 8086. Most of the emulators provide
- the equivalent of an 80286 running in real mode, which is a little different
- than an 8086. Most applications however do not use these instructions for
- portability reasons.
