x86 processors do indeed begin in Real Mode, but you would usually stay in Real Mode only during the run of the bootloader. If you use something like GRUB for the bootloader, then it already spits you into Protected(/Long?) mode; if you go this path, you don't really have to worry about Real Mode and segmented memory.

The segmentation is allways there, and even though the segment registers are not present in the code, they are in the mashine code. Im intrested in this because im writing a small for fun OS with my friend and its quite important to understand how it all works. |
