APM NH.SYS: Difference between revisions

Revision as of 15:01, 1 March 2020

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 a Intel chipset.

 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.
