It isn't really an OS, it doesn't have the layers or the infrastructure of an OS. It's just a shitty app that can do a few pre-programmed things and those don't even work. They call it an OS because it runs without needing an OS. But that doesn't make it an OS itself. Before EFI you could just write machine code into the boot sector of any disk and the BIOS would boot from it. This used to be totally normal. My first machine was an MSX computer and it didn't really have an OS. You'd have Basic for doing stuff, or you'd plug in a cartridge and it would run the code on the ROM inside that.
so what ur saying is, I can run doom with no OS? ๐ค
Yep, here's UEFI-DOOM.
Although UEFI isn't as low-level as the BIOS stuff, but I couldn't find a BIOS port of DOOM so UEFI will do.
