What are major differences between Real Mode Programming and Protect Mode Programming? Also is there a good book out there that explains how protect mode programming works, because I got a couple of assembler books, but all of them refuse to talk about protect mode programming. WHy? BM

You may find this document of some interest: http://www.execpc.com/~geezer/os/pm.htm

It gets pretty indepth, so I''m going to post a link to it.

http://www.nondot.org/sabre/os/articles/ProtectedMode/

That has a good amount of articles that should cover what your looking for.

The most noticable difference is the memory model - Real-mode is a p.i.t.a., protected is verra naice.

In the hay-days 386enh Win16 was the primary way to access protected mode as well as something called DOS4GW which was made by Watcom and is now discontinued IIRC.

There''s a free IDE called masm, and tutorials on how to use it (search for masm and Icezillain), which is for programming Windows in x86.

I think SAMS published a book called "Make your own 32 OS" which covered protected mode asm.

That was Make your own 32-bit OS (in 24 days? ), but other than that you''re right.
