Abstract
This invention is directed to enhancement of flexibility when connecting an add-in card conforming to the PCI-Express specification. More specifically, the operation mode of the system board of a printing apparatus is configured to cope with both a root-complex and end-point. When an add-in card is inserted into an extension slot, the type of add-in card is discriminated by confirming the ON state of a detection pin. When the inserted add-in card operates as a root-complex, the system board is set to operate as an end-point. When the inserted add-in card operates as an end-point, the system board is set to operate as a root-complex.
Claims10
A printing apparatus capable of functional enhancement by mounting an add-in card, comprising:
- a discrimination unit constructed to discriminate whether or not the mounted add-in card includes an I/O expander;
- and
- a setting unit constructed to set an operation setting mode of a controller of the printing apparatus as a root complex in a case where said discrimination unit discriminates that the mounted add-in card does not include the I/O expander, and set the operation setting mode of the controller of the printing apparatus as an end-point in a case where said discrimination unit discriminates that the mounted add-in card includes the I/O expander.
An operation setting method of a printing apparatus to which an add-in card is mounted, to achieve functional enhancement by inserting the add-in card, comprising:
- discriminating whether or not the mounted add-in card includes an I/O expander;
- setting an operation setting mode of a controller of the printing apparatus as a root complex in a case where it is discriminated that the mounted add-in card does not include the I/O expander;
- and
- setting the operation setting mode of the controller of the printing apparatus as an end-point in a case where it is discriminated that the mounted add-in card includes the I/O expander.
