Manuals are big, static things which see "punctuated evolution" rather than frequent changes. Readme files, bulletins, and web advisories supercede info in the manuals, as was recently distributed to the ADSM-L readers by IBM. Stay attuned to all information sources. As the Readme says: "For IBM Tivoli Storage Manager v5r2 and later releases, AIX Operating System version 4 is not supported since it is scheduled to go out of service at the end of 2003. The Publications for IBM Tivoli Storage Manager v5r2 were frozen before the decision was made to not support AIX 4.3 with this release if the Storage Manager." Richard Sims, http://people.bu.edu/rbs
