I am still hoping for dbootstrap to get a NewWorld compatible `Make bootable from the hard disk' function but for now this patch makes things accurate for now. I also added at least one link to mac-fdisk-basics.txt but im not sure exactly the right way to include that document, i think it would be helpful to have in the debian install docs. you can find it at: http://www.alaska.net/~erbenson/doc/mac-fdisk-basics.txt -- Ethan Benson http://www.alaska.net/~erbenson/
