Q: What are the Driver Services Library (DriverServicesLib) and the Multiprocessing Nanokernel (MPLibrary)? Which Apple Macintosh models do and do not support them?
A: These two libraries provide much of low-level services and functionality available to driver and application developers. Driver Services Library controls the support of functions enumerated in "DriverServices.h" and described in "Designing PCI Cards and Drivers for Power Macintosh Computers." The MP Nanokernel provides low-level process control, timing services, and memory services as described in "Adding Multitasking Capability to Applications Using Multiprocessing Services."
The following chart indicates whether Driver Services Library (DSL) and the MP Nanokernel is present in a specified machine family. All listings refer to the entire machine family unless otherwise noted.
