Thank you for the info, this is really a learning experience for me. Ok, I am under the impression that only dos machines can read dos made cdroms, ie, unix os can't utilize a dos based cdrom because I was told, cdroms, some of them that is, have some special type of index or coding that only dos can get at and emulate, so a lot of cds cannot be used by unix-based operating systems. I was wondering if there is a standard manner in which companies make each specific disc 'proprietary' or is it just that unix based systems cannot emulate effectively the ISO-9660 format? (Does that make sense?) Vic
