PC Assembly Book (2006)

I decided to base the course on the free NASM (Netwide Assembler) and the free GNU gcc compiler (however, any 32-bit C compiler would work). The tutorial only covers programming under 32-bit protected mode and requires a 32-bit protected mode compiler. I have example code files for: DJGPP, Borland, Microsoft, Open Watcom and Linux C compilers.
