Hi! Is anyone into power management, specifically how to properly idle DOS applications NOT using any of the DOS calls typically triggering DOS idle handling?
FreeDOS EDIT does not use any DOS functions in its event handling loop, but instead does its input polling through INT16 (keyboard) and INT33 (mouse). First guess on saving some energy would be to issue HLT instructions as part of the event loop, but I am not sure about the side effects on doing so from within an application. May it safely be used? Further, there seem to be some idle related interrupts, like INT28 [1]. But the FDAPM documentation mentions that this interrupt is not hooked, unless its ADV:MAX mode is used [2]. As this is not the default, relying on INT28 seems neither to be a good idea.
