So tried making a symlink today in several different variations, but none of them did what I wanted to do. That being said I found that I can start the update process by simply double clicking the bin file "updateSystem" from the directory on the cd. So while I have been unable to get the icon to work with the USB CD-ROM I ultimately accomplished what I wanted which is to be able to do the updates from the USB CD-ROM. I'll keep playing around with it, but I'm pretty happy with where I'm at now.
Thanks so much for all the help Gryd3. I really appreciate it.
