Chapter 14 80386 Real-Address Mode


The real-address mode of the 80386 executes object code designed for execution on 8086, 8088, 80186, or 80188 processors, or for execution in the real-address mode of an 80286:

In effect, the architecture of the 80386 in this mode is almost identical to that of the 8086, 8088, 80186, and 80188. To a programmer, an 80386 in real-address mode appears as a high-speed 8086 with extensions to the instruction set and registers. The principal features of this architecture are defined in Chapters 2 and 3.

This chapter discusses certain additional topics that complete the system programmer's view of the 80386 in real-address mode:
