That will be the solution for that CD, tough a Linux system or even a Windows
one will also be helpful.
I don't want to act as a teacher, but this is often little known
( better and deeper explanations available on the net):
I'm posting this hoping it will spread ...
CD have a basic data structure known as ISO9660 which is merely a
specification on how data can be written and read to/from CD.
Since it dates Old Good DOS days filenames will be 8.3;1 uppercase.
Newer or smarter OS needed better handling of filenames so many "extensions"
were created, each one has it's followers and mantainers, and incompatibilities
These externsion usually permit: Long Filenames, File Permissions, Deeper
Directory Nesting, File ACL, ...
So whe could have a CD using
ISO9660 basic
ISO9660 extended
ISO9660 + RockRidge ( Unix Systems )
ISO9660 + Joliet ( Windows System )
ISO9660 + RockRidge + Joliet ( Custom build )
ISO9660 + HighSierra FileSystem ( Old SunOS )
ISO9660 + HFS ( Mac ? )
UDF ??
more ??
You can see the that you can always access CD data using the ISO info,
but some other info lies hidden inside the extensions. Sad to say each
OS has the choice to implement a personal set of these.
AIX only reads Rockridge, Windows only uses Joliet, Linux should be
able to read both, ...
When burning a CD care should be taken when choosing the extensions
to put along with ISO so that a CD can be read on most systems.
You may usually find Windows+Mac CD, but Unix+Windows are much more difficult
to find, usually because Windows CD Mastering Software never targets unix systems.
My personal solution is to use and suggest using "mkisofs/cdrecord" on all Unis
systems : AIX, Linux, Solaris, ... and Windows to build the ISO images you need
to burn on CD. This way you can build multi-system CD.
