The less you know about it, the less you need to know.  At least thats how I
see it.  I haven't had any problems that I could trace back to being in
protected mode.  Protected mode is actually easier to understand than real
mode.  In real mode, you have segments, data segments, near and far
pointers, conventional memory, extended memory, expanded memory, tiny,
small, medium, large, and huge memory models, etc.  In protected mode, you
just have flat memory.  In protected mode, you just have to remember that
you can't go poking around in memory with pointers (i.e. direct video RAM
access).  If your program sticks to its own data, you shouldn't have a
problem.
