The reason is that practically all modern machines have broken MP tables now and the only option is acpi tables. That means, the only way to disable acpi in a system now would be to explicitely put *acpi=0 in plan9.ini. This might be neccesary for some early machines like T23 (and my P4 machine also had this issue) that do have ACPI tables but they are unusable for interrupt routing. The FQA would need to be amended. -- cinap
