A method of initializing programmable devices on a shared bus, comprises, on power up, loading control instructions on a processor from an attached tangible, non-transient computer-readable medium, automatically allowing a first programmable device on a common bus to exit its reset state and enter a read-to-program state as the computer system powers up, automatically holding a second programmable device on the common bus in its reset state, querying the common bus by the processor to identify the first programmable device, copying the contents of a program image file by the processor from the computer-readable medium across the common bus to the first programmable device, and once the first programmable device has been programmed with the contents of the program image file, signaling the first programmable device to release the reset hold on the second programmable device. |
