View source for APM NH.SYS

Replacement APM driver (APM_NH.SYS)
APM_NH.SYS is based on 10.037 level of IBM's [[APM.SYS]] (same as XR_D002). Its purpose is to honour the APM hooks installed by VIAAPM.SYS while allowing usual APM tasks such as power-down or suspend mode. It is therefore essential that one installs APM_NH.SYS rather than APM.SYS, so the KT266A idle hook would not be taken out by IBM's driver.
 DEVICE=APM_NH.SYS

'''Tip:''' In System which only have ACPI it is reported that APM-NH.SYS works even it is a Intel chipset.
