4-2 Virtual Media
CD-ROM/ISO 9660 Images
UNIX and UNIX-Like OS
To create an image file, make use of "dd". This is one of the original UNIX
utilities and is included in every UNIX-like OS (UNIX, Sun Solaris, Linux). To
create a CD-ROM image, copy the contents of the CD-ROM to a file. You
can use the following command:
dd [ if=/dev/cdrom ] [ of=/tmp/cdrom.image ].
In this case, "dd" reads the entire disc from the device "/dev/cdrom" and
saves the output in the specified output file "/tmp/cdrom.image". Adjust both
parameters exactly to your needs (input device, etc.).
MS Windows
To create the image file, use your favorite CD imaging tool. Copy the whole
contents of the disc into one single ISO image file on your hard disk. For
example, with "Nero," you choose "Copy and Backup", and navigate to
the "Copy Disc" section. Select the CD-ROM or DVD drive from which you
would like to create an ISO image. Specify the file name of the ISO image
and save the CD-ROM content in that file.
