	Jan, 

	You're right ... I don't need far pointers winth a 32-bit offset. 
What I really need is to point a pointer to a certain portion of the 
memory. I'd like to make a pointer to video memory area, to tell you the 
truth. I tried somethink like:

	char *p;

	p=(char *)(0xb8000);

	... but I've got a SIGSEGV signal. Since I've never worked with 
protected mode, I don't know how to do that work.

	Regarding to peek/poke, these commands refers to memory positions, 
while inportb/outportb refers to ports. They are diferent !!

	Thanks anyway.
