Well, I suppose I can make the bios cache it's contents into any unused segment
that I want, that it can get to that is. And that would easily make the bios
code available to me in the 32bit linux environment. But alas, it doesn't do
squat for helping me to write the code back to the chip because the REAL bios
is out of reach. Oh well. I'll just DOS boot and use debug as before when I
want to bios hack I suppose. :) Thanks to all who gave input, I appreciate
your efforts
