   Ok, so just for the record.   
      
   It was well-known by 1985 that at least SOME 8086 programs   
   (in all memory models, even huge) could be run on the 80386   
   and have a 512 MiB address space, but absolutely no-one saw   
   any advantage to 512 MiB vs 1 MiB and would prefer that   
   ALL their 8086 programs be restricted to 1 MiB for a number   
   of years and then completely fail.   
      
   At least no-one in the northern hemisphere. The northerners   
   had the knowledge, but zero requirement. And that is why   
   they didn't bother to inform dumbass southerners that   
   if you ever want to address 512 MiB on this new 80386   
   thing us northerners just produced, all you need to do is   
   go into PM32, max out the selectors, set the D bit appropriately,   
   and a couple of other things, and you're done and dusted.   
      
   So instead we had to work it out for ourselves, and it took   
   a full 36 years.   
      
   I'm actually from Queensland, which is (supposedly) 20 years   
   and 1 hour (due to refusal to adopt daylight savings) behind   
   the rest of Australia. Maybe that needs to be updated to 36   
   years and 1 hour with regards to understanding the capability   
   of the 80386.
