Is this just an issue of changing the drives physically or are there
some sort of master slave switch that I have to change as well?
I believe that with SATA, the concept of master and slave is gone. If
the cables will reach, you could just switch the cables, otherwise
switching the drives would work. You probably should switch the drives
and try to boot Mac OS X on the "b" drive to see if that works before
bothering with the linux install.
