BTW the handbook is great. I started with 3.5 and it (the handbook) just gets better and better. I read that paragraph to mean turning off ACPI and was not aware of APIC. I was told when debugging a sound card problem that I should turn off ACPI because my laptop was getting error messages. My understanding of this advice was that ACPI along with an older BIOS could cause interupt problems. If this is true perhaps both should be mentioned.
