This operation can not be possible since you need 2 processors in order to boot 2 desktop boards, you can not boot 2 different desktop boards with a single processor.
I just want to use the unused processors of other motherboards by connecting then on single BUS.
Then how can i do that ?
I am afraid that his operation can not be possible, as I explained you before, your need a processor install on both desktop boards in order for the system to boot.
Computer cluster is loosely coupled system.
I want to create a tightly coupled system. Consider the example of IBM Blade Server.
I want to implement similar concept using old motherboards.
The IBM blade center contains up to 14 separate servers connected to 2- gigabit Ethernet switch as the primary interconnect.
The system uses 4 common power supplies, 2 blowers and 2 Chassis management modules to allow for remote management.
The backplane provided the electrical interconnect for the devices and a private 100m Ethernet management channel to the components.
A secondary fabric could be used to add 2 additional switches for Gb, Fibre channel or inifinaband.
If your trying to mimic the interconnect on this system, all you need is a simple dual gigbit network.
The blades were frequenly used indivulally as part of a IT infrustucuture. One for DHCP, one for mail, one for SAP, etc.
Or as parts of a standard cluster.

I want to use the processors of old computers into a single unit so that the processing power is increase.
Since their is no use of old processors if used individually.
I just want to combine the processing power.
Any Suggestions how it can be done ?
