Ahh, this is currently not supported in FreeBSD. > I want to write a process that will dynamically evoke power management > events. So you want to write a program like 'apm', which lives in /usr/src/usr.sbin/apm. Also check out /usr/src/usr.sbin/apmconf, which is the 'controlling' program for the apm driver which lives in /sys/i386/apm/apm.c > 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.

Does this mean you've got the PCCARD driver working under FreeBSD now? > Any information source on how to program for the APM Driver and APM BIOS > interface will be appreciated. Check out the above sources, and also look for the APM specs somewhere on Intel and/or Microsoft's site. Nate
