Depends on context. In the early days many s100 users assembled the boards themselves and doubtless wouldn't have blinked any eyelid at hacking 8080/z80 bios code if they needed to (I remember the first kid at school to get a computer around that time, programmable with physical switches, binary LED display). By the time the commercial software market for CP/M became established with killer apps like word star, the users would have been rightly horrified by bios hacking.
