Abstract: A method for identifying hard disks connected to one or more ports of a computing device. The computing device comprises a controller. A first serial-number of each of the hard disks read by the controller is received. A second serial-number corresponding to each drive letter of the hard disk assigned by an operating system of the computing device is read. The first serial-number and the second serial-number is compared to determine associations between the drive letters and the hard disks. The associations are displayed on a display device connected to the computing device.

Abstract: A method tests hard disk ports located on a motherboard of a computing device. Each of the hard disk ports connects to a respective serial port of a test fixture. The test fixture includes a group of serial ports, a multiplexer and a storage device. Each of the hard disk ports is selected to be tested during the process of hard disk ports test. A data transmission path is formed by building a connection between the storage device and a channel of the multiplexer corresponding to the hard disk port. Data are written to the storage device and read from the storage device through the data transmission path. The hard disk port is working normal if the written data are identical to the read data. The hard disk port is not working normally if the written data are not identical to the read data.

Abstract: A method for testing hard disks under an extensible firmware interface (EFI) provides a device tree of hard disks. Nodes of the device tree represent block devices or file systems of the hard disks. Devices paths and handles corresponding to each of the device paths are obtained from the device tree. Parent controller handles of each of the device paths are obtained. If there are parent controller handles the same as the obtained handles, the parent controller handles the same as the obtained handles are deleted. The computer determines that a number of the hard disks is equal to a number of the device paths corresponding to the remained parent controller handles. Nodes information of each of the device paths corresponding to the remained parent controller handles are determined as hard disk information of each of the hard disks.

Abstract: A system and a method for switching functions of A Universal Serial Bus (USB) flash drive includes setting a bilateral switch under a first triggered status represents that the USB flash drive is in a boot mode, and under a second triggered status represents that the USB flash drive is in a memory mode. The switching method further includes a determination of whether the USB flash drive is in the boot mode, according to the triggered status of the bilateral switch. The switching method further includes controlling the host controller to access data in a flash memory in the USB flash drive, if the USB flash drive is in the boot mode; or controlling the host controller to access data in a main flash memory section in the flash memory if the USB flash drive is in the boot mode.

Abstract: A power switch control device includes a control chip connected to power switches distributed in a room, and a microcontroller connected to the control chip. When a person gets through an entry/exit door of the room, both of a first sensor fixed to an interior surface of the door and a second sensor fixed to an exterior surface of the door sense the person. By comparing record times of the two sensors, the microcontroller can determine whether the person enters or exits the room. If the person enters the room and a count value is changed to one from zero, the microcontroller sends a power-on command to the control chip to switch the power switches on. If the person exits the room and the count value is changed to zero from one, the microcontroller sends a power-off command to the control chip to switch the power switches off.

Abstract: A system for automatically testing motherboards includes a test server (1), client computers (2), and a network (5) connecting the test server with the client computers. The test server is for storing a plurality of high-level OSs (Operating Systems), test programs and test script files, for setting contents of test configuration files, and for storing test results. Each client computer has a motherboard installed therein, and is operated under a DOS (Disk Operating System). The client computer downloads and installs a high-level OS from the test server, downloads and installs one or more test programs and a test script file according to a test configuration file set by the test server, executes the test script file to auto-run test programs in a sequence specified in the test configuration file, and then transmits test results to the test server.

Abstract: A system for controlling power sources of motherboards under test through networks includes a central server (1), a serial device server (3), a bus distributor (4), a number of power controllers (5), and a number of testing computers (8). The central server sets testing parameters, and transmits instructions regarding turning on or off power sources of the testing computers to the serial device server, in order to control the power sources of the testing computers. The serial device server converts the instructions into serial instructions, and generates corresponding serial signals. The bus distributor distributes an address for each power controller, receives the serial signals, and transmits the serial signals to corresponding power controllers. Each power controller turns on power sources of corresponding testing computers in which motherboards under test are installed according to the received serial signal. A related method is also disclosed.
