Advanced Power Management (APM 1.1, 1.2) device driver provides support for APM BIOS interface.

DEVICE=x:\OS2\BOOT\APM.SYS <parameter> 

Parameter:

  • /B - favorizes the direct connection to the APM-BIOS support
  • /D - favorizes the device-driver connection of the APM support
  • /V - x.y forces the compatibility to APM Version x.y (e.g. 1.0)

Together with the APMDAEMN.EXE these settings can also be done by using the Power-Symbol from System Setup Folder.

TIP
Battery Setup
  1. Change WarpCenter properties to 'Show only when Mouse is over Center's position'
  2. Enable in 'Power Properties' from System folder 'Performance' page 'Automatically change performance when the power source changes'. (Only tested with Warp 4 fixpak 13).
TIP
When OS/2 fails to install in ACPI-only systems REM this driver (has to be done on the Installation disks too) or give APM_NH.SYS a try, it is reported to work on Intel based motherboards too.
