From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Seconding that's a not-how-things-were.
The lovely thing with legacy architectures (6502, 68k, x86, z80, etc.) that were in use during that time is that they were very very simple: all you needed to do was put executable code on a ROM at the correct memory address, and the system would boot it.
There wasn't anything required other than making sure the code was where the CPU would go looking for it, and then it'd handle it from there.
Sure, booting an OS meant that you needed whatever booted the CPU to then chain into the OS bootloader and provide all the things the OS was expecting (BIOS functions, etc.) but the actual bootstrap from 'off' to 'running code' was literally just an EPROM burner away.
It's a lot more complicated now, but users would, for the most part, not tolerate removing the ability to boot any OS they feel like, so there's enough pressure that locked shit won't migrate down to all consumer hardware.
There was still real competition in the x86 OS space back then, also. Like IBM had OS/2 and DOS 7, and made hardware, so they certainly wouldn't want it locked to a Microsoft OS.
Oh yeah: there were a stuuuupid amount of OSes.
On the DOS side you had MS, IBM, and Digital Research.
You also had a bunch of commercial UNIXes: NextStep, Solaris, Xenix/SCO, etc. along with Linux and a variety of BSDs. There were also a ton of Sys4/5 implementations that were single-vendor specific so they could sell their hardware (which was x86 and not something more exotic) that have vanished to time because that business model only worked for a couple of years, if that.
There was of course two different Windows (NT, 9x), OS/2 which of course could also run (some) Windows apps, and a whole host of oddballs like QNX and BeOS and Plan9 or even CP/M86.
It was a lot less of a stodgy Linux-or-Windows monoculture, and I miss it.
I ran OS/2 Warp as my primary for like a year, I loved it, and it could even play many Windows/DOS games with fiddling
....I still have some OS/2 (or, rather, ArcaOS) systems running here.
Mostly for a very limited subset of things that never really migrated across to "modern" windows - I have a BBS running on there because 16 bit DOS apps on OS/2 was pretty much the best way to run them when it was 1994, and in 2024 it's still the best way to deal with them.
