I'm actually a far cry off assembly programming. GDB would probably work, if
you mean watching for certain output and relaying it back to you. I can
probably serve as a somewhat more intelligent monkey that tries things and
reports how they came out. :)

Is it possible to still achieve something under these circumstances? Like for
example having the Grub developers prepare code that I can run and report what
happened?
