i am resending the patch to dbootstrap.sgml to document the bootstrap
installation procedure for NewWorld powermacs, the new procedure is
slightly less painful (especially for SCSI or slave IDE installs)
given the advancments in the newer ybin utility (now packaged). 

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:
