| Prev | Chapter 14 Introduction to Protected Mode | Next |
The Goal is to learn the basics of protected mode to prepare you for later MPs in ECE 291, where you'll be using the tools and concepts you learn in this tutorial. By the end of the tutorial, you should be familiar with the following:
The differences between real and protected mode on the x86 architecture.
The purpose of DPMI, and how to use it from protected mode.
How to write a protected mode program in assembler with the help of DJGPP.
How to use the PModeLib functions, and how some of them work internally.
