Does anyone have an idea why RL9.3 does not boot on IBM 8284:

I’m trying to replace old CenOS installation. Some other distros (Fedora, Ubuntu, Debian) did not have such problem.

Is this a power8 box? If it is, then power 8 is likely not going to work. Rocky 9 is what works and is supported on power9.
