Are you familiar with https://old.reddit.com/

How much longer do you think Reddit will keep an option that doesn’t maximise end user engagement metrics?

It’s right there in the name:

Basic Input Output Operating System

It’s the first stage of whatever os you run.

If you don’t think the BIOS is part of your operating system, just remove it and see how far you get on the next boot.

Edit: I was always told the I in BIOS was “I/O”. WAS I DECEIVED FOR ALL THIS TIME!?
