Write to it, if your program crashes, you don't!
Well, if you have the memory location, is this memory location
a physical address? Your program can only see addresses that
are assgined to it in the LDT and GDT and they are all logical
addresses. If it's a physical address you're tring to write to,
you would need to find the descriptor in the LDT/GDT that has it
and then use the selector and write to it's logical address.
What exactly is the situtation.
