Depending on which bios you use, it will either load it at 0000:7c00 or 
07c0:0000 which are both the same areas in memory. However, there's an 
important difference here: your offsets will get screwed over if you don't 
make sure you end up in the right segment. The method I've used in my OS is 
to make a far jump to make sure I'm in 07c0:0000 and not in 0000:7c00. I 
discovered this because my own BIOS has this problem.
