A structure for combining a printing circuit board with a rack comprises a fixing sheet, a plurality of supporting seats and buckling sheet; the fixing sheet and the buckling sheet are respectively at the opposite sides; the fixing sheet has a level section, a positioning pin is disposed at the lower side of the level section; another pin is disposed at the top end of the supporting seat proximate to the buckling sheet; a buckling tenon is disposed on the top end of said buckling sheet; the fixing sheet, the supporting seats and the buckling sheet are used to fix the printing circuit board without needing other screws and screw drivers, the printing circuit board can then be allowed to combine with or separate from the rack. Whereby, the combination or the detaching operation can be more convenient, the production time and cost can be saved.

A method and a device for controlling data transmission between IDE apparatuses allow an IDE controller of an IDE control device to send read control signal to an IDE apparatus via a set of IDE interfaces and a signal control transmission line and then to send write control signal to another IDE apparatus via another set of IDE interfaces and another signal control transmission line. Thus, the output data from the IDE apparatus through the data transmission line can be accelerated the transmission speed thereof between IDE apparatuses so as to save the time for transmitting data.

An interface controller mounted in a SCSI hole includes a circuit board and a panel. The circuit board is associated with a chip, an IDE interface male plug and control circuit. The panel is disposed at a lateral side of the circuit board and has a size adapted to the SCSI hole and being joined to an inner side of the SCSI hole. The panel is associated with an inserted recess so as to be fixed to a used casing of an independent CD-ROM drive or hard disk drive with SCSI socket for saving production cost.

An IDE connector with opposite male plug and female socket includes a circuit board with a control circuit, a chip, a male plug and a female socket. The male plug is joined to one side of the circuit and the female socket is joined to another side of the circuit board so as to be disposed oppositely. The female socket is connected to the male plug of an IDE device to enhance the data transmission quality between two IDE devices and decrease using of the flexible flat cable.
