Abstract: Digital-to-analog (DA) conversion circuitry with a simplified testing circuit includes a DA converter to which test data, initially “0”, may be applied. The DA converter feeds an analog voltage corresponding to the test data to a voltage holding circuit. Subsequently the test data is incremented to “1” and then converted to a corresponding analog voltage by the DA converter. A comparator compares the analog voltage corresponding to the test data “1” with the previous analog voltage held in the voltage holding circuit and corresponding to the test data “0”. When the test data is sequentially incremented by 1 (one) at intervals, the voltage output from the DA converter is higher than the voltage held in the voltage holding circuit while the DA converter operates normally. The function of the DA converter can be easily, rapidly tested by monitoring the output of the comparator.

Abstract: A multi-leg stand mainly includes a vertical main tube and a tripod structure connected to a lower end of the main tube. The tripod structure includes an inner tube around which a locking element and three unions are sequentially mounted from top to bottom. Three legs are separately connected at inner ends to the three unions. When the locking element engages with the first union at a first locking position, the three legs are folded to locate at the same side of the main tube, and when the locking element engages with the first union at a second locking position, the three legs are equally angularly spaced and radially extended. And, when the locking element is in a releasing position on the inner tube, the three unions may be freely turned in one direction with only one hand to quickly and accurately move into the folded or the spaced position.

Abstract: A method and computer system for accessing initialization data stored in a boot ROM's memory space which is not used by a BIOS contained in the boot ROM. After the power supply starts up, the south bridge starts up and sends an initiating signal to the north bridge for starting up the north bridge. Once the north bridge has started up, it sends the south bridge a transaction which requests that the south bridge reads the initialization data from the boot ROM and sends the initialization data to the south bridge. Then, the CPU starts up and operates normally after the CPU receives an initiating signal and the initialization data sent by the north bridge.
