Unfortunately, they are not in a package in the 5.0 DVD, so if you get the DVD you would have to identify the files and copy them across to the HDD.
I feel that the install.sh script is for Redhat Linux and the file structure like whrere the kernel modules are kept etc. in Redhat and Debian will not match. So the install.sh needs to be modified which will reflect correct path names and file names as applicable to Debian. I can post the contents of the install.sh script if required.

As for searching the files on DVD as suggeested by JonnyH, I do not have the DVD version and hence could not try it out.[/b]
