Hello Mitsuru! :-) I wanted to ask the list and make sure, in general, if OID can be optional/missing depending on the hardware capabilities. It looks like things are like that - some other OID are missing as well depending on the hardware. I think one general remark could be put into acpi and sysctl manual pages, something like: "Note that some OID will be available only if given hardware supports them, on a different hardware these will be missing which means that feature is not supported." > Unfortunately, UPS is not covered by ACPI specification.

I thought acline would be such place - it is even specified in the manual (unlike battery) :-) Now I know assumption must be made that is acline oid is not available then we have a dekstop. But I dont really like assumptions, thats why I prefered to ask first :-) Thank you! :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info _______________________________________________ freebsd-acpi@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscr...@freebsd.org"
