IMAGE FORMING APPARATUS, STARTUP CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM ENCODED WITH STARTUP CONTROL PROGRAM

摘要

An image forming apparatus includes a main processing portion set as a root complex of PCI Express, a startup control portion to control startup of the main processing portion, and a connection portion connectable with an option board having a sub processing portion set as a root complex of PCI Express. The startup control portion includes a detection portion to detect the option board connected to the connection portion, an acquisition portion to acquire ability information about the option board at a stage before the main processing portion starts up, when the option board is detected, a selection portion to select one of the main processing portion and the sub processing portion, based on the acquired ability information, and a switch portion to start one selected from the main processing portion and the sub processing portion as a root complex.
