I downloaded DJGPP a couple of days ago to take a look and have the same
problem. It mentioned that the first 1Mb of physical memory was mapped to
E0000000 so I tried writing to E00A0000, it didn't crash but I saw no
output. I don't want to use the drivers included, I want to write my own.
 
Is there anybody seriously using DJGPP for game developement out there? If
so could someone with a few answers put together a mini faq or something as
I see a lot of people with questions like this.  

Thanks,
