There is a version that runs natively on x86 hardware (through it's a 32-bit system, aimed at older hardware; my newest x86 hardware is over a decade old and I've not had time to work much on a 64-bit system & drivers). See konilo.org/x86
Yeah, but how do I get that running on an old x86? Boot from a floppy somehow?
There is a floppy image on the x86 page. I also have multiboot compatible kernels linked there for use with GRUB or similar bootloaders.
