That just means the drivers are present, it doesn't mean they are used. It looks like you have 'device acpi' in your kernel config. The way to tell that ACPI is enabled is to look for an acpi0 in your dmesg. Alternatively, you can run devinfo to list your device tree. If pcib0 is a child of acpi0, then you are using ACPI. If it is a child of legacy0, then you aren't. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
