I think you’re right in inferring that OP is confusing DOS with BIOS but technically, plenty of old computers and early video game consoles like the Atari 2600 didn’t have a BIOS and would immediately execute the code on the tape, disk, or cartridge. Some old computers had bootstrapping but that’s not really BIOS in the IBM sense.
