  In assembly, I noticed that the segment selector, gs, points to
the conventional memory area. It is normally pointed to by
_go32_conventional_mem_selector(). I have successfully accessed video
memory area at 0xA0000 using the segment selector in gs.
  My question is: Is it safe to use gs as the conventional memory
selector? At what conditions will gs change? Someone posted a question
similar to this a while ago, and I have not seen any answer yet. Any
insights will be appreciated.
