Abstract
This disclosure relates to personal computer systems, and more particularly to a personal computer which provides for interrupt redirection of the activity of a microprocessor. The personal computer system has a multichannel bus for transferring data, a microprocessor for manipulating data and coupled to the bus, and a plurality of input/output devices coupled to the bus for receiving and delivering data for manipulation by the microprocessor. Each input/output device is capable of generating a logical interrupt signal indicative of a request for access to the microprocessor and of being remotely reset to a non-interrupt condition, and all of the devices deliver their logical interrupt signals through a common physical channel of the bus. An interrupt controller is coupled to the microprocessor and bus for recognizing delivery of an interrupt signal and for periodically generating an interrupt reset signal and delivering reset signals to all of the input/output devices simultaneously for setting all of the devices to a condition indicative of no request for access to said microprocessor.
