Posted December 5, 200915 yr This article targets the user who wants to know how the CPU works. I explain some assembly basics, the real, the protected and the long mode. Assembly working code is included so you can test yourself how the processor works in real mode, how protected mode is entered, how we get to 64-bit mode and finally, how to exit from all them and go back to DOS. Do you dare to follow? Let's go!/>http://www.codeproject.com/KB/system/asm.aspxTed.
