Re: 64-bit bootloaders

Have you tried it?  I just downloaded it via the Github repo at 
https://github.com/ReturnInfinity/BareMetal-OS

It appears to use NASM instead of GAS, but I'm not sure which version to try.  
Compiling under Debian/wheezy/amd64 gives all sorts of interesting compilation 
errors:

$ nasm fat16.asm -o fat16.sys
fat16.asm:170: error: impossible combination of address sizes
fat16.asm:170: error: invalid effective address
fat16.asm:177: error: impossible combination of address sizes
fat16.asm:177: error: invalid effective address

I'll take a look later, but wondering if you have a working build environment 
before I dig deeper.  It looks like its intended to be built on Windows, 
judging from the lack of Makefiles.
