`ABSTRACT
`A computer system for multi-processing purposes. The com
`puter system has a console comprising a first coupling site and
`a second coupling site. Each coupling site comprises a con
`nector. The console is an enclosure that is capable of housing
`each coupling site. The system also has a plurality of com
`puter modules, where each of the computer modules is
`coupled to a connector. Each of the computer modules has a
`processing unit, a main memory coupled to the processing
`unit, a graphics controller coupled to the processing unit, and
`a mass storage device coupled to the processing unit. Each of
`the computer modules is Substantially similar in design to
`each other to provide independent processing of each of the
`computer modules in the computer system.

`devices such as a printer and other output means. Moreover,
`the PC can include special audio output devices such as
`speakers the like.
`PCs also have easy to use keyboards, mouse input devices,
`and the like. The keyboard is generally configured similar to
`a typewriter format. The keyboard also has the length and
`width for easily inputting information by way of keys to the
`computer. The mouse also has a Sufficient size and shape to
`easily move a curser on the display from one location to
`another location.
`Other types of computing devices include portable com
`puting devices such as "laptop' computers and the like.
`Although somewhat Successful, laptop computers have many
`limitations. These computing devices have poor display tech
`nology. In fact, these devices often have a smaller flat panel
`display that has poor viewing characteristics. Additionally,
`these devices also have poor input devices such as Smaller
`keyboards and the like. Furthermore, these devices have lim
`ited common platforms to transfer information to and from
`these devices and other devices such as PCs.
`Up to now, there has been little common ground between
`these platforms including the PCs and laptops in terms of
`upgrading, ease-of-use, cost, performance, and the like.
`Many differences between these platforms, probably some
`what intentional, have benefited computer manufacturers at
`the cost of consumers. A drawback to having two separate
`computers is that the user must often purchase both the desk
`top and laptop to have “total computing power, where the
`desktop serves as a “regular computer and the laptop serves
`as a “portable' computer. Purchasing both computers is often
`costly and runs “thousands of dollars. The user also wastes a
`significant amount of time transferring software and data
`between the two types of computers. For example, the user
`must often couple the portable computer to a local area net
`work (i.e., LAN), to a serial port with a modem, and then
`manually transfer over files and data between the desktop and
`the portable computer. Alternatively, the user often must use
`floppy disks to "Zip' up files and programs that exceed the
`storage capacity of conventional floppy disks, and transfer the
`floppy disk data manually.
`Another drawback with the current model of separate por
`table and desktop computer is that the user has to spend
`money to buy components and peripherals which are dupli
`cated in at least one of these computers. For example, both the
`desktop and portable computers typically include hard disk
`drives, floppy drives, CD-ROMs, computer memory, host
`processors, graphics accelerators, and the like. Because pro
`gram Software and Supporting programs generally must be
`installed upon both hard drives in order for the user to operate
`programs on the road and in the office, hard disk space is often
`wasted.
`One approach to reduce some of these drawbacks has been
`the use of a docking station with a portable computer. Here,
`the user has the portable computer for “on the road use and
`a docking station that houses the portable computer for office
`SC.
`Similar to separate desktop and portable computers, there
`is no commonality between two desktop computers. To date,
`most personal computers are constructed with a single moth
`erboard that provides connection for CPU and other compo
`nents in the computer. Dual CPU systems have been available
`through Intel's slot 1 architecture. For example, two Pentium
`II cartridges can be plugged into two 'slot 1' card slots on a
`motherboard to form a Dual-processor system. The two
`CPU's share a common hostbus that connects to the rest of
`the system, e.g. main memory, hard disk drive, graphics Sub
`system, and others. Dual CPU systems have the advantage of

`
`The present invention relates to computing devices. More
`particularly, the present invention provides a system includ
`ing a plurality of computer modules that can independently
`operate to provide
