APM NH.SYS: Difference between revisions

Latest revision as of 23:45, 22 September 2022

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=\OS2\BOOT\APM_NH.SYS

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