Yes, and assembler files, but other people have made modifications, and
supply their own versions.
There are ports from MASM ( which Chuck used ) to NASM and GAS.
I have tried not to change the binary, but for my next version ( 2.0 ) I am
changing some of the kernel names, hence my original post.

This sounds good! I was trawling the net the other day for a decent 80x86
dis-assembler. Most were awful!
I will take a look...

I think this could be very useful to dis-assemble the BIOS...
