Otherwise, could anyone suggest me an alternative way? Thank you, Thanasis ...

Let's say I have a piece of code that runs fine on an OS. Now, if I install that OS on a virtual machine (server virtualization), and run that code on that, is it possible that the code behaves differently? If so, what are the prerequisites for that?

1) A usermode process has its own "address context", which maps the user-mode virtual addresses to a unique collection of physical page frames. That is, the meaning of any particular virtual address changes from one moment to the next as the Windows XP scheduler switches threads. Part of work of "switching threads" is to change the page...

I am studying Intel Protected Mode. I found that Call Gate, Interrupt Gate, Trap Gate are almost the same. In fact, besides that Call Gate has the fields for parameter counter, and that these 3 gates have different type fields, they are identical in all other fields. As to their functions, they are all used to transfer code control into...
