Abstract: A method for recovering a basic input/output system (BIOS) memory circuit in a computer system is disclosed. The method includes steps of providing a memory device comprising a first basic input/output system memory circuit and a second basic input/output system memory circuit, the first basic input/output system memory circuit and the second basic input/output system memory circuit respectively having a first computer program and a second computer program stored therein, wherein the first basic input/output system memory circuit and the second basic input/output system memory circuit are employed to initiate an operation of the computer system, enabling the second basic input/output system memory circuit upon booting the computer system, detecting if the first computer program includes an error, and re-programming the first basic input/output system memory circuit based on the second computer program when the error is detected in the first computer program.

Abstract: The purpose of the present invention is to provide a method for displaying an information of updating a basic input output system (BIOS) of a computer system, wherein the computer system having a specific configuration is initialized by a computer program stored in a basic input output system (BIOS) memory.

Abstract: There is provided a method and device for identifying failed devices in a computer by displaying messages indicative of failed devices in the computer with a single luminescent display. A BIOS memory having a plurality of memory locations containing data values representing a series of computer program instructions for testing hardware devices in the computer is provided to test the hardware devices in the computer. If the hardware device in the computer such as RAM, BIOS memory or display adapter is tested to be failed or contains error, the single luminescent display will be driven to blink ON and OFF at different frequencies to respectively indicate individual failed device in the computer.

Abstract: A connector device includes a housing mounted on a mother board and having a slot for receiving a daughter board. A retainer is used for securing the daughter board to the housing, and includes a base having a channel for receiving the daughter board, and a seat having a bore for slidably receiving a latch. A spring may bias the latch to engage with the daughter board and to lock the daughter board to the base and the seat of the retainer. The latch includes an end portion having an angled surface for allowing the daughter board to move the latch against the spring.

Abstract: A connector seat of a computer bus has four side walls. Each of the four side walls has two adjacent side walls. The connector seat is formed with at least two openings each located between one of the four side walls and each of its two adjacent side walls, so that the one side wall is capable of being oscillated outward. Thus, when the user swings or oscillate the bus connector so as to remove the bus connector from the socket of the connector seat, at least one of the side walls of the connector seat may be oscillated with the bus connector, and will not be broken due to the stress or pressure produced when the user swings or oscillates the bus connector.

Abstract: A mainboard having a selective connection COM/VGA jack layout includes a specific area for connecting different jack terminals to connect peripheral devices. The specific area includes two different sets of jack layouts to form a COM port jack layout and a VGA port jack layout laid in a juxtaposed manner. Manufacturers or designers may select to connect a COM port jack terminal or a VGA port jack terminal based on requirements (such as whether with VGA ONBOARD or not) so that only one type of mainboard is needed. Production cost may be reduced and production process is simpler.

Abstract: A connector device includes a housing mounted on a mother board and having a slot for receiving a daughter board. A retainer is used for securing the daughter board to the housing, and includes a support having a channel for receiving the daughter board, and a latch slidably received in a base and to be maintained relative to the base at either a working position to engage with the daughter board, or a non-working position to disengage from the daughter board. The daughter board may be easily engaged into the housing when the latch is located at the non-working position.

Abstract: A supporting device includes a housing for receiving one or more batteries. A spring blade has a middle flap and an end limb secured to the board, and includes a bent segment for engaging with the batteries. Another spring blade is engaged through the board for attaching to the circuit board, and includes a panel for detachably securing the battery to the housing. The board has two legs for spacing the board from the circuit board.

Abstract: A server having an air flow guide device includes a support frame, a fan set mounted in the support frame, and an air flow guide device including a guide body mounted in the support frame and located behind the fan set. The guide body defines an air flow guide region. Thus, the air flow guide region of the guide body may guide and collect the air flow produced by operation of the fan set, so as to provide a heat dissipation effect to inner parts of the server.

Abstract: A common module for DDR SDRM and SDRAM on a motherboard, which computes and determines the resistance of the terminators on the motherboard so that the work current is controlled within the range allowed by an SDRAM controller, and can achieve the object of a DDR DRAM and SDRAM common layout without the need of an extra quick switch IC.

Abstract: An over temperature protection method and its circuital device for a central processing unit includes a read and write memory unit having pre-stored therein; an instruction for identifying a type of CPU and automatically predetermining the maximum allowable over temperature for the CPU. An over temperature is detected by a heat sensitive resistance installed at the space immediately under the CPU to cause an audio frequency alarm circuit to output a sound alarm and also cause the CPU to slow down its operation speed to an appropriate reduced rate to prevent CPU from being damaged by over heat or other loss caused by interrupting CPU operation. After recovery of temperature to a normal value, the CPU can be instructed to operate with its normal speed.
