- Adjust timings in WaitOnBaseBusy, WaitForDrq, WaitShortForDrq to match old atapi driver. Thanks Caemyr for testing and finding optimal values (which are slightly below the values used in this commit). The proper solution would be to implement adaptive delays scaling.
See issue #4995 for more details.
