Regarding the installation of EDT software, I overlooked a note from the install.pdf  file.

The gist of it is that if the scripts do not run, then remount the CD-ROM by typing the

following:

mount /mnt/cdrom -o remount,exec

which will then allow the scripts to be run. The directory /mnt/cdrom should be changed if

the cdrom is mounted somewhere else. (The note can be found in the page 1 of the file

install.pdf.)

Unfortunately I don't have linux installed at the moment so I cannot test this. My computer was

reinstalled with Windows XP, the previous CentOS system being wiped out. However if this works,

then there is probably no need to copy the files to the hard drive.
