We use ACPI on AMD64 so you should be parsing the ACPI tables not trying to rely on legacy interfaces which if I rememeber the spec rightly aren't even guaranteed safe to call when ACPI is active.

Assuming you even have a BIOS - you may have EFI underlying or Linuxbios or be a virtual machine. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
