"Fixing the bug means enabling a code path, that was dead for a long time.
Both my computers did not complain, yet, the fixing might trigger some
effects (think of hidden BIOS bugs on some machines, uncovered by the now
executed code). So removing the floppy probing and not supporting
drive types any more, is an option as well."

I wrote this to Jeroen a few days ago and it seems to anticipate what
Okuji-san said now. OK, if there are buggy machines that do not survive the 
probing, of course, you might not use it, even at the expense of a tiny group
of users of rare hardware. I agree with that approach.
But, to me, there are still questions open. IMHO code (at least comments)
should reflect the intention of the programmer. So if we intend not to use
floppy probing (which I understand), why do we keep it in the code, even call it
under strange circumstances?
In what way is the format of stage 1 fixed, so that we cannot modify or, at
least, extend it? In other words, what depends on stage 1 so strongly, that
we have to leave it as it is? (By the way, the idea of Thierry to include a
geometry parameter came across my mind too, when thinking about a floppy stage
1. If including it created about zero costs, I would have suggested it here).
I would like to learn about the inner working of GRUB and really appreciate
to get some hints.
