Loosely Coupled Multi-Processing Method for Personal Computers

      Described is a hardware and software extension that provides a
loosely coupled multi-processing capability for Personal Computers
(PCs).  The extension enables co-processors to run cooperative
applications among multiple processors within one system that has
shared file system support.

      The loosely coupled multiprocessing method described herein
pertains primarily to PC networking systems, such as the IBM PS/2
Model 95 xp 486 with an Aox MicroMASTER 486 co-processor using OS/2*
software, however the concept is applicable to similar computer
systems.  The concept describes an extension that provides the
capability to install multiple Aox MicroMASTER 486 adapters in a PS/2
95 xp 486 system and to run OS/2 software on each of the processors.

      The extension enables each Aox MicroMASTER 486 co-processor to
provide the ability to download and load the OS/2 program.  The local
memory area is shared with other processors, thereby allowing direct
memory sharing.  Also, the extension enables the co-processor to have
the ability to interrupt any other processor so as to provide
efficient interprocessing communications.

      The Figure shows a block diagram of how the Aox 486 MicroMASTER
interconnects to the planar processor.  The Aox 486 MicroMASTER
co-processors are loaded by a command from the planar processor
within the PS/2.

      First, the OS/2 loader, kernel, and Mini-FS...
