I have a doubt regarding real and protected mode in X86 processors.
"Is software jumping from p-mode to r-mode just a hack? Is the CPU designed to do this? If this is so, is it not possible for a user to write code to crash a secure OS irreversibly?"
If you can't help me, please try to ask any of your friends at bosch.
