That's what we did too.  However, there is another way -- move all
the CD contents to a harddrive and rename the "index" hdf file.  ENVI
wants to leap into that *.hdf suffix no matter what you call it when
it comes time to input the image.  We confirmed this from EDC and
through trail and error here.  Hopefully the next version will get it.
