When installing from diskettes or CD-ROMs, the installation programs sometimes fetch data from information files located on the first installation diskette. This file contains the media's identification information. During the installation process, these programs normally check the current directory for all necessary install files. If the program consists of two or more diskettes or CD-ROMs, which you have copied into a single directory prior to registration, you do not need to make any modifications. If there are multiple media and you have registered each media individually, you need to modify the volume labels of the install information file (*.INS or *.INF) to point to the files in the Software Package Library structure. For example, if the volume labels are given in numerical order ("VOL_LABL1", "VOL_LABL2", and so on.), they should be changed to \1.VOL "VOL_LABL1", \2.VOL "VOL_LABL2", and so on. The modified *.INS or *.INF file should then be registered along with the installation program as an added item procedure after the initial library item is registered. For more information on registering added item procedures, see Defining Added Item Procedures.

Modifications made to Linux or UNIX programs depend on which Linux or UNIX environment and release level you are using. In general, you should:
