Problems solved by technology

[0003] At present, some expansion connectors can support the transmission of two data formats. In the process of using, if the format of the signal transmitted by the main board is not the same format as the inserted expansion card, the expansion card will not be able to be used, or even will be burned

Abstract

A mainboard with an expansion connector comprises a central processor, the expansion connector, a selector switch and a platform control unit. The expansion connector is used for inserting an expansion card in a separable mode. Transmission of a first bus signal and transmission of a second bus signal are conducted between the selector switch and the central processor and between the selector switch and the platform control unit respectively. The selector switch is electrically connected with the expansion connector, and the transmission of the first bus signal or the second bus signal is selectively conducted between the selector switch and the expansion connector.

Description

technical field [0001] The invention relates to a mainboard, in particular to a mainboard with an expansion connector. Background technique [0002] In Intel's latest Patsburg platform, its Platform Controller Hub (PCH) integrates a Serial Attached SCSI (Serial Attached SCSI, SAS) controller, which can be better applied to server and storage motherboards. In actual use, when the Patsburg platform requires a large capacity of storage space, it is often necessary to set an expansion connector on the motherboard, through which an additional SAS expansion card can be connected to obtain sufficient capacity of storage space. [0003] At present, some expansion connectors can support the transmission of two data formats. In the process of using, if the format of the signal transmitted by the main board is not the same format as the inserted expansion card, the expansion card will not be able to be used, or even will be burned. Contents of the invention [0004] In view of the ...
