Source. The exact provenance of this upload was not recorded at the time. Documents of this kind on this wiki come from the mirrors where the IBM PC and PS/2 technical library survives — the Ardent Tool of Capitalism (ardent-tool.com), ps-2.kev009.com, minuszerodegrees.net and the Internet Archive. The file has been checked against the printed document's own title page, part number and edition notice, which are quoted above; those, not the filename, are what identifies it.

Licence: not free. This is IBM service and technical documentation. IBM never released it under a free or open licence, and copyright remains with International Business Machines Corporation (or, for the later ThinkPad volumes, with Lenovo). It is hosted here for preservation and for repair reference on obsolete equipment, on the same basis as the rest of this wiki's manual collection. It is not public domain, and it is not licensed for redistribution — if you need a copy for commercial use, that is a matter between you and the rights holder.
