MP 1,1-5,1 Can't Install Any OS Mac Pro 1.1

[destroyfish]

Same story as everyone else who gets an old Mac Pro, got it online from some guy, has a login with an unknown password and I can't get into recovery mode.

I did at one point get the keyboard keys to work, but I think now they don't. I've been trying to use El Capitan USB installer, followed the terminal instructions of creating one. I made a Monterey Open Core Patcher Installer, I even got to use the bootcamp installer, none of these worked. In fact, the fans ramp up and sounds like a jet engine when I assume, the installer is trying to be read.

I don't know what I should be doing to just fresh install an os. Can anyone give suggestions?

I tried looking for my specific problem but I hate Apple naming conventions, I don't know what is what. All the naming conventions and the variety of different solutions to everyone's problem, I would prefer a straight to the point answer, which thankfully you had one. I have trouble reading too so if there is too much writing going on I get dizzy.
