ACPI didn't make it possible to break the OS's reliance on the firmware, but it did make it possible to rely on it to a much lesser degree. The key way it did this was through the introduction of ACPI source language (ASL) and ACPI machine language (AML). ASL and AML allowed the firmware to communicate to the OS the steps necessary to perform actions on its platform, but then the OS was responsible for actually executing them.
