Abstract:
1. A computer comprising: a first I/O expansion card comprising: a first interface card slot for selectively accepting an first interface card; and a first configuration message generator configured to provide a first bandwidth configuration message corresponding to the first interface card slot; a second I/O expansion card comprising: a second interface card slot for selectively accepting a second interface card; and a second configuration message generator configured to provide a second bandwidth configuration message corresponding to the second interface card slot, wherein the first and the second bandwidth configuration messages are different; and a motherboard comprising: an I/O expansion slot for accepting the first I/O expansion card or the second I/O expansion card; a chipset coupled to the I/O expansion slot so as to be connected to the first interface card slot of the first I/O expansion card or the second interface card slot of the second I/O expansion card through the I/O expansion slot; and a configuration setting circuit coupled to the chipset and the I/O expansion slot, the configuration setting circuit configured to obtain the first bandwidth configuration message or the second bandwidth configuration message through the I/O expansion slot and set an internal interface-card-bandwidth configuration in the chipset based on difference between the first bandwidth configuration message and the second bandwidth configuration message.
