I first have to find out what LBA exactly is. If LBA deals with 256 sectors
and 256 heads, then LBA is equivalent to lineair coding which simplifies
things a lot.
Unfortunately most disks I have laying around are < 500 MB :( So I cannot
use LBA anyway (for the moment).

That is correct. But now I need someone willing to translate this equation
in ML. The only way _I_ know how to do multiplications is by doing a loop of
addititions. And I know that this certainly not the fastest way. So therefor
my plea for help.
Same for the division-stuff.

The most important thing for me is the TTHS/Lineair conversion. Once I know
how this is done, I could do the Lineair/BAM conversion myself.
