Here is a risky method but it does work to change RAMdisk size while the machine
is on.  Go to the Control-Panel and change your RAMDISK size (this process will
kill all your ramdisk data but since you are taking it out I guess you won't 
mind). then hit option-OA-Ctrl-Reset (the system test) and then IMMEDIATELY
type ctrl-OA-Reset (Warm Boot).. Your RAMDISK is now changed... You cannot wait
too long though because if the SELFTEST gets past 20000, it will be messing
with battery ram and you could mess up your clock and battery RAM.  I am not
sure how many other bad things it does to the system so I am not one to use it
Does anyone else have any comments on how dangerous this is?. Another idea
is to exit from Diversi-Copy, I know that it kills all of the data in your
ram disk but I am not sure if it will reset the size of it or not...
