 I have the exact memory position the boot seems to jump to at home, but
 not here, sorry. somewhere near $218000 if not my memory is wrong.
 Ofcourse, if you want to change something in the block $210000 - $21ffff
 you have to erease the whole block and write it again, so if you are to
 do this, be really really shure you rewrite it correctly or you will be
 fucked. (or your calc at least, and not litterly speaking, so you can't
 use it to loose your virginity, sorry)
