This code isn't relevant to "optimal geometry".  It is very simple:

        if (A > (C+1) * cyl_size)
                return 0;

That's all!  A == end address, C == end cylinder.  These cryptic names
are used to make the maths readable.

We're only talking about 8 megabytes, worst case, right?
Does anyone really care?

Is the geometry on Amiga relevant for booting, etc.?
