In the case of the drivers that are the necessary part for the hardware to work correctly and the software that accompanies them and that are only useful for the hardware for which they were created, it could be said that they are directly linked. That is to say, if you don't have, for example, a Sound Blaster 16, its drivers and software are not interesting or useful to you, but if you do have one without its drivers and software, it could not be used either. And also the drivers and software corresponding to a piece of hardware were distributed together with it, so downloading an ISO of a CD of those drivers and software would be the same as downloading your own backup.
One example, although there are many others from the time, the case of the Rebel Moon Game for the 3D Blaster, is not very useful if you don't have that graphics card, which I think only exists in that version. But if you are the lucky owner of one of those cards, would it be piracy to use an ISO downloaded from the internet because you don't have the original CD that came with the graphics card?
It is only a question and opinion, without the intention of offending, my apologies if it is so.
