Oh, no, I hadn't been able to tell from your ASL that bit 16 was set (it's not that easy to guess as it computes the ID's dynamically at runtime. I was merely guessing that since I had changed the matching logic to look at bit 31 that that was the cause, but it wasn't the matching logic that was different (comparing _ADR to _DOD), but the logic that parsed _DOD is what treated your laptop differently. -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "[email protected]"
