The invention discloses a double-mainboard
personal computer and a using method and
system thereof, and relates to the technical field of
computer hardware integration, and the method comprises the following steps: identifying a drive activation operation in a preset area range of a display; activating an analog switch when it is identified that the drive activation operation is obtained;
uSB interface connection corresponding to the computer main board is established, switching activation of the first computer main board and the second computer main board is achieved, and the corresponding computer main board is the computer main board corresponding to the preset matching direction. The invention solves the technical problems of weak security isolation mechanism, low
system switching efficiency, easy
data transmission leakage and insufficient security when the existing
computer technology is used for coping with complex office requirements, and achieves the purposes of realizing security isolation and efficient switching of the double mainboards, requiring no intermediate transfer equipment for
data transmission, reducing the cost and the like. The interaction security between the two hosts is ensured while the transmission is efficient and instant, the
isolation effect is improved, and the computer use security and the office efficiency are improved.
