APM aware applications register with the APM Driver using an operating
system dependent mechanism.
This is not exactly what I meant.  Sorry!   8o

I want to write a process that will dynamically evoke power management
events.  All power management features not supported by the APM Driver
(there will be some because the platform I am working is a superset of APM
1.2) will have to be controlled by this process as well.  If this means I
must enhance the current APM Driver for BSD then that is what I will do. 
Any information source on how to program for the APM Driver and APM BIOS
interface will be appreciated.

thanks
