IBM PC DOS 7.1 has been made available for download. On the IBM ServerGuide Scripting Toolkit download page, the "Feature overview" said "The ServerGuide Scripting Toolkit includes IBM PC DOS 7.1". (The bundled User Guide PDF file said the same thing.) Actually it seems it does not contain all of the software that one would expect to find in IBM PC DOS 7.0 or PC DOS 2000, so either this is a limited release of IBM PC DOS 7.1 (which it doesn't say), or this is the full IBM PC DOS 7.1 release but IBM PC DOS 7.1 doesn't have all of the same features as earlier versions of the PC DOS software. Therefore, I wouldn't necessarily recommend IBM PC DOS 7.1 over PC DOS 7 or PC DOS 2000 as an operating system to be content with. However, since any differences are likely meant to be bug fixes or improvements, it would make more sense to replace some files from PC DOS 7 with the PC DOS 7.1 files, such as the boot files. (The bottom of page 74 User Guide makes it seem like the _BOOT_HD.NOZ file is valid in "as a base option for PC DOS 7.1 only", although I suspect that might have been meaning to distinguish from other software on the disk, and not trying to say that PC DOS 7.0 didn't have the option.) Just keep in mind that mixing versions of DOS executables can often easily result in complaints about being run from a different DOS version.
On Thursday, July 26, 2007 (11:00am PST), one could go to IBM page and find a menu. At the top, one's mouse could hover over "Products", then over "Systems & servers", and select System x (xSeries). In the "What we offer" box was a link titled "Systems Management software" that went to IBM Systems Management. In that "What we offer" section, under "Deplay", were links for IBM ServerGuide and ServerGuide Scripting Toolkit. The latter was a link to IBM Systems Management - IBM ServerGuide Scripting Toolkit where one could click on ServerGuide Scripting Toolkit Downloads to get to a page titled "IBM Support - IBM ServerGuide Scripting Toolkit version 1.3.04 - Servers".
The page had links that included:
Next statement from that file: "You may 1) use the Program up to the level of use specified in the PoE and 2) make and install copies, including a backup copy, to support such use." There is no limit to the number of copies it says I can make, as long as it is supporting "the level of use specified in the PoE". Earlier in the document, it says "A "Proof of Entitlement" ("PoE") is evidence of Your authorization to use a Program at a specified level." The evidence I have is in the very file, as IBM authorizes me to a license as long as the I acquired the lawfully.
The license also says that "all applicable export and import laws and regulations" must be followed. (Not just laws, but regulations too.)
As for distribution, since I do not identify myself as being "Either IBM or its reseller", I do not see where I am specifically authorized to create a PoE for another. In fact, the license also forbids me to sublicense the program. The permission to use the software at all is entirely coming from the license that would apply to anyone reading the license who obtained the software legally. However, the license would not be granted if copyright law was violated in order to provide someone with the software. Furthermore, the document says I "may not" [...] "distribute the Program except as provided in this Agreement". I should be able to distribute the software in any method, but only if that method is provided for in the agreement.
Since the agreement does provide for me to make copies that support "me" (where I am a person or individual legal entity, defined in the document as the term "You") using the program, I can make copies for my own use. However, if the copies are meant for someone else, then I haven't yet identified any provisions in the agreement to allow the creation of such copies, and so it appears that such copies would not be created in a method that is compliant with the license.
Since any other authorization to distribute the software isn't specified in this document as far as I know, except to say that apparently I don't have such authorization, distributing the software might only be able to be done when obtaining the software from an authorized distributor, which might only be the IBM corporation (oer perhaps also one who can identify as being "its reseller").
