This is about the AS/400 which is an IBM mini-computer launched in 1988. It lives on today after several name changes and considerable hardware and software changes. It is still often informally called the AS/400 but this is about the early days when that was still the official name. OS/400 was its operating system and the two were tied to each other.
I read, back in the 1990s, that there was a special system program which if deleted would trigger the O/S to uninstall itself during the next IPL (boot). The idea was that an IBM engineer could delete this program if they detected that the system was unlicensed. I think that I read this in an official, reliable source but I cannot be sure after so long. I have been unable to find confirmation. Certainly, IBM took the licensing issue seriously and I am aware of several serious disputes but not the use of this nuclear option.
Can anyone confirm this as true?
Can anyone confirm it as an urban myth that I fell for?
