So if the machine actually has MPS support, you'll probably get the same result with "acpi=off". (of course if it doesn't have MPS, then acpi=off would boot in uniprocessor legacy PIC mode) cheers, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
