Which is to say, it may or may not work. That's built into the definition of "unsupported". If memory serves, early z9s shipped with some I/O and crypto cards that were the same as those on the z990 (which is supported by OS/390 2.10). Later z9s had new cards. It will most likely be those newer cards that won't work with OS/390 2.10. It's a real roll of the dice, but I guess folks running in these Officially Unsupported environments already know that and accept the risk. I also find it very strange that there are generally available IBM-provided PTFs floating around that add the needed function. It sounds more like some back alley code obtained from someone who has paid for an extended support contract. But what do I know? I'm not in the z/OS or VSE support organizations....
