Hope so!  I'll install it tommorrow and try it.

The issue was not with GRUB loading 16bit code, it can and does load 32bit
code.  The issue was the Windows compiler doing something that prevented it
from being used with GRUB.  Perhaps it put win32 specific stuff in the code
or something like that, I don't know (I did use options to tell it not to
link the default executable startup routine, and linked it with a customised
asm routine later on).  All I know is that when the code was compiled with
the DOS version it worked and when compiled with the windows version it
didn't.

There are supposed to be Ada 83 compilers floating about that compile to
real mode (someone pointed me to where to purchase a copy a while back,
before I got to grips with grub  -- I was going to write my own
bootloader)).
