Subject: Low memory access

  I have seen DJ himself say that starting with version 2.0 you will no
longer be able to use 0xE0000000 to access the first meg of memory.  Is this
going to hold true for 0xD0000000 accessing video memory as well?  
  My guess is that it is, so we all will have to rewrite our video routines.
Anyway, if we get the selector for linear memory from the go32_info_block
structure at the very beginning of our program, are we assured that the
selector will be valid (and won't change) for the duration of the entire
program?  It would be a pain to keep accessing the go32_info_block everytime
I wanted read from or write to video memory.
