Ah.. it sounds logical yes. But not for DOS where the CPU was not waiting, but instead just burning CPU cycles. Try running DOS in any VM and you'll be shocked

Ah.. it sounds logical yes. But not for DOS where the CPU was not waiting, but instead just burning CPU cycles. Try running DOS in any VM and you'll be shocked by the CPU usage. A constant 100% until you install a little program called DOSIDLE that properly runs a HLT instruction when the CPU is waiting.
