Are there are BIOS updates for your motherboard? Yes, and I have the latest non-beta version (v1019 (dated 2004-11-08) for P4P800 mutherboards). > 2. Do you have ACPI 2.0 support enabled in the BIOS (I was reminded of this because some ASUS MBs default this setting to off -- which may or may not cause problems with FreeBSD)? Yes (also, I've just tried disabling ACPI 2.0, with no luck).Received on Mon Oct 31 2011 - 01:46:00 UTC
