Abstract
A method for configuring a plurality of configurable components within a computer system. The method includes the step of asserting a RESET signal for all of the configurable components. The RESET signal is asserted by a diagnostic processor within the system. The components each respond with an ERROR # signal which provides an indication to the diagnostic processor that the component is in an inactive state. After a predetermined number of clock signals the diagnostic processor configures a first component, then a second component and so forth and so on, until all of the components are configured. After all of the components are configured, the diagnostic processor deasserts the RESET signal for the first component, then deasserts the RESET signal for the second component and so forth and so on, until all of the RESET signals have been deasserted. Each component deasserts the ERROR # signal upon the deassertion of the RESET signal. The diagnostic processor allows normal operation to occur upon the deassertion of all the ERROR # signals.
