Hi! Yes! The good news is that newer FreeDOS kernels even have a simple version built into the kernel itself. [..] Good news! Well, I should have googling for FreeDOS idle CPU, instead of DOS idle CPU. ;) :-) However, the normal way to let the CPU idle while DOS is idle is to load a

I read, that the source of CPU (over)heating problems under original MS/PC-DOS was the fact, that its waiting for key-loop (or however it is called) didn't set CPU idle, when user (or application) was idle. For example: when the computer has been left with the cursor blinking in the command line.
