Do machines need BIOS? a minimal hardware control architecture might consist of an on/off switch, and a recover-mode switch for when the machine fails in a panic or hardware fault.

So, let's start with no assumptions about the hardware except that there is at least one CPU (we'll call it the boot-CPU -- a vonNeumann machine with addressable memory that is waiting for a word consisting of a instruction (op-code) and/ior data, having at least) that has reviewed the hardware for us and left us with some data about the machine in its registers or a special memory address.

Given that, we'll assume that the boot CPU has loaded and executing our kernel instructions.

I'm going to wait until THERE'S MORE ORDER to AMERICA. Done...

Okay. What is the proper op-code or instruction set for a processor on a general purpose machine?
