You can use Rufus: https://rufus.ie/en/

To modify the ISO to turn off hardware check and TPM support for Windows 11 to install it on an unsupported PC.

Besides Linux and BSD Unix there is: https://reactos.org/ https://aros.sourceforge.io/ https://www.haiku-os.org/ and https://www.arcanoae.com/arcaos/

I know some third-world nations still use DOS and the BORLAND DOS compilers because people donate old computers to their nations.

With the right OS, old computers are still usable. Please don't throw them away, e-cycle them so they get used by poor nations that cannot afford new PCs.

If interested, please take a look at its up-to-date evolution

I tested on real hardware too, and it worked well

Have you checked out Haiku? It's so delightfully early 2000s.

Bro you clearly haven't use HaikuOS before.

Back when I used a debian based distribution I made use of https://bedrocklinux.org/ to make use of the AUR. It's not for everyone though.

Now this is interesting... apparently it is possible to run Nix AKA "The Nix Package Manager" on Alpine -- despite the fact that Alpine is Busybox and Musl based and NixOS is Coreutils and Glibc based!

Well done Nix engineers and contributors!

(I may switch to Alpine w/Nix Package Manager in the future, depending on how well it works!)

Bedrock Linux: https://bedrocklinux.org/

Sure, just install Bedrock Linux and add the Arch stratum on top

There's a Bedrock Linux distro already...

Bedrock Linux. It is allows you to make a system out of various seemingly-incompatible parts of other distros. I haven't gotten around to trying it myself, but it's really cool.

If you want to actually use multiple distributions at once integrated tightly into each other (like using Ubuntu with AUR packages) I highly recommend https://bedrocklinux.org/. It uses some chroot and symbolic link magic to share files across filesystems.
