CA 2328560

A method of controlling the power-on of a computer system by providing a plurality of monitor lines interconnected with respective components of the computer system, monitoring the lines using a logic control circuit in response to a power-on reset signal, and executing a system power-on sequence in response to a determination by the logic control circuit that the components of the computer system are functioning properly. In the embodiment wherein the computer system has a plurality of CPU slots which may receive a system CPU or a terminator cartridge, the logic control circuit determines that one of the system CPUs or terminator cartridges is plugged into each of the CPU slots, and can further determine that a properly matched CPU cartridge has been installed into the system, and that multiple CPUs contain compatible power supply requirements. The logic control circuit can also determine that the main power supply has been properly connected to the system motherboard, and that all daughter cards are properly installed on the motherboard and power supply connections to the daughter cards have been properly installed. Finally, the logic control circuit can determine that a power regulator (such as a voltage regulator module or on-cartridge power regulator) is functioning properly.
