Read the FAQ ;-)
It simply changes the attributes of the selectors used by your program in a way 
that you aren't limited to the size of your program when using pointers. 
Normally the ds selector is limited to the memory in your heap so you can't 
write outside it, when you call this function this limit is "removed" (read 
changed).
