Hi! Idlehalt is just a small routine, it may not contribute to the idle statistics shown by FDAPM. I guess it might even make those look lower if you use both in parallel. You could check which apps you use which fail to let your CPU go idle with FDAPM. Maybe there are possibilities to tune apps or settings.

In particular when other operating systems manage voltage and clock themselves anyway, it would only affect DOS :-) Regards, Eric _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
