You're wasting your time. The Pi was not designed to run anything other than Linux.
That might be the case now but I very much doubt it was the case for the Pi 1. IIRC the original Raspbian released back then was a third party effort to get Debian booting on the Pi.
The original desing was based on building a low cost, networked machine for educational use with the expectaton of seling no more than 20,000 units.* The choice of ARM (via the BCM2835) was determined by factors like cost and availability not by which OS it would ultimately run.
We got Linux because someone outside RPTL/RPF was willing to put in the effort to port it. The only closed source stuff then, as now, was the GPU bootloader. And, IIRC, parts of the GPU driver tough not so much now.
We could have had Windows if MS wanted to port it. We could have had RISCOS (the second OS for ARM after Arthur). We could have had MacOS if Apple had been interested. Or a different Linux distribution. Or a propritary minimal OS come programming language as used in the 8 bit days (think a Pico with the micropython REPL, a screen, and keyboard) that inspired the whole Pi concept.
Raspbian got there first. RPL later forked it and improved on it and have been doing so ever since.
*: That's on record but I don't have the links to hand to support my claim. Sorry.
