Is #ELKS (8086 linux) still a thing? Would the #book8088 be a good machine for it?
I suspect the #XTCF BIOS wants a DOS4 style partition table so i dunno if the old 8086 UNIXes (#coherent, #xenix, #minix) would cooperate.
Then there's the whole issue of installing such a thing on a machine that doesn't support floppy drives... 😝
