Firmware determines during a boot of a computer, if a bus enumeration is needed or if the computer can be booted quicker by skipping a bus enumeration. The firmware performs a bus enumeration if this a first boot or if the bus has had it infrastructure changed since the previous boot. For buses that have only fixed resources coupled to it, then the bus configuration cannot change. Also, for buses that do not have only fixed resources, the infrastructure may be probed to determine if the bus configuration has changed. If there is no change, bus enumeration is not needed. Metadata is created, updated and stored in flash memory involving the bus infrastructure. Since the metadata is stored, a bus enumeration is not needed to gather information about the bus when no change has occurred.
