摘要： A server motherboard diagnosis method, system, and related circuit system. A management module of the server motherboard and peripheral devices managed by the management module are capable of being powered by a server power source and a USB port. In response to the management module and the peripheral devices being powered by the USB port, a power supply line of the server power source is isolated, as by: identifying the peripheral devices, in response to the management module and the peripheral devices being powered by the USB port; for each of the identified peripheral devices, initializing the peripheral device, and then shutting down the power supply of the peripheral device; establishing a communication between the management module and a diagnosis host through the USB port; and executing a command in response to the command being received from the diagnosis host.

摘要： A system includes a CPU including a primary address decode logic module (PADLM) and a plurality of diagnostic registers, wherein the PADLM includes address bus inputs, and an enable input port. The system further includes a data flip-flop having a data input coupled to a master enable signal line, a set input coupled to an interrupt signal line, an output coupled to the enable input port of the PADLM, and a clock input. Still further, the system includes an address decode logic module having a memory address input and an output indicating whether the memory address is within a predetermined address range of the diagnostic registers, wherein the output of the address decode logic module is coupled to the clock input. Memory mapping is enabled in response to receiving an interrupt signal and determining that the memory address is within a predetermined range of memory addresses for diagnostic registers.
