It's highly dependent on the motherboard used. It's one reason why I avoid BIOSTAR motherboards on the desktop -- they have a seriously broken APIC/LAPIC setup that requires disabling the ACPI setup just to run any modern Linux kernel. Let us know what make/model of that laptop that has the broken LAPIC setup. -- Kelly "STrRedWolf" Price http://strredwolf.furrynet.com _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
