Systems, methods, and computer-readable storage media are provided for parallel initiating of devices in a system. The method includes generating an affinity table that stores option ROM execution data including first data associated with a first device and second data associated with a second device and triggering, based on the affinity table, a first initialization of the first device and executing a first option ROM code during a pre-boot phase and triggering, based on the affinity table, a second initialization of the second device and executing a second option ROM code during the pre-boot phase. Triggering the first initialization of the first device and triggering the second initialization of the second device during the pre-boot phase is performed such that at least a part of the first initialization of the first device and at least part of the second initialization of the second device are executed in parallel.
