    摘要: A preboot execution environment (PXE) test device includes a microprocessor, one or more indicators, a network interface, a power connector, and a storage device. The network interface connects the PXE test device with a computer. The power connector connects an external power source to supply a voltage to the PXE test device. The storage device stores a boot loader, an embedded operating system, and one or more programs. The microprocessor executes the boot loader and the embedded operating system to start the PXE test device. The one or more indicators indicate a power supply status and a starting status of the PXE test device. The microprocessor further executes the one or more programs to remotely boot the computer for test PXE of a network card in the computer.

    摘要: In a system and method for testing a serial port of a computing device, the serial port electronically connects to a test fixture. Test data is sent to a receive data (RXD) pin by a transmit data (TXD) pin. A test result is received from the serial port by the RXD pin. The TXD pin and the RXD pin work normally if the test data is identical to the test result. When voltages of a request to send (RTS) pin and a data terminal ready (DTR) pin are set at high level, the RTS pin, a data carrier detect (DCD) pin, the DTR pin, a ring indicator (RI) pin, a data send ready (DSR) pin and a clear to send (CTS) pin work normally, upon the condition that status values of the serial port indicate the voltages of the above six pins are at high level.

    摘要: 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.

    摘要: A test fixture includes a first RS-232 connector and a second RS-232 connector. The data terminal ready (DTR) pin of the first RS-232 connector is connected to the DTR pin of the second RS-232 connector, and the clear to send (CTS) pin of the first RS-232 connector is connected to the CTS pin of the second RS-232 connector. The DTR pins are further connected to a power pin of each of the test computers. The test fixture sets a high level voltage for the connected DTR pins, and sets a low level voltage for the connected CTS pins according to the commands of turning on the test computers sent by the control computer, to turn on the test computers. An auto shutdown software included in each of the test computers is executed to shut down the test computers.
