Can code damage hardware?

Can random code damage your hardware when run in Real Mode? If yes, give some examples how. What happens when the ACPI tables are overwritten? Is it possible to disable the CPU fan through code, and have the CPU overheat and break, or does the BIOS have moron-proof failsafes incase someone would do that?

How the hell do you think microprocessor realtime cooperative multitasking works?

Except it must be more complex, since, first, you have IO interrupts that still have to be processed asynchronously, second, if you are doing the entire displaying manually, you have to do that asynchronously in the timer interrupt(s), third, you might have long-running tasks which would require wasting a lot of cycles to check if it's not the time to yield to achieve necessary responsiveness. Not to mention being really, really careful about that, too careful than is acceptable for life-critical applications.

By the way, C for a microcontroller? I lol'd.
