I recently installed Linux, a version of unix for the PC, in addition
to my regular dos partition.  This comes with a small program called
"wini" which is a program, which occupies the MBR to allow me to
choose which OS I would like to boot into.  It's my understanding
OS/half does somethign like this, also, or can do something like this.
If FDISK/MBR REWRITES the MBR with the basic, boring code that
normally is there with DOS, then if I use this method, I will destroy
the wini program, and restrict myself from booting into my Linux
partition.  This is another drawback to fdisk/mbr.
