Knowledge Base Main

Purpose

The purpose of this document is to provide instructions on how to use the POST cards that are included within the PC-Doctor Service Center kits.

Description

  1. Attach the remote display to the PCI/miniPCI POST card using the included cable.
  2. Make sure the system is shut down and insert the PCI/miniPCI POST Card in an available PCI/miniPCI slot.
  3. Turn on system power and observe the POST codes in the 2-digit LED display.

    Note: POST codes are unique to each PC manufacturer. You can obtain these codes from technical support websites for the related PC manufacturer, or visiting http://www.pcdservicecenter.com/biospostcodes
  4. Use the button on the remote display or on the main card to select the detail reading shown on the 3-digit LED display. The top row of LEDs indicates the current reading. The available detail selections are:
    • MHz: Shows the system bus frequency in MHz
    • -12V: The -12V power rail reading
    • +12V: The +12V power rail reading
    • I/O: The voltage of the I/O bus which will be 5V or 3.3V depending on the system
    • Auxiliary: The auxiliary voltage reading (normally 3.3V)
    • +3.3V: The +3.3V power rail reading
      ·+5V: The +5V power rail reading

The yellow LEDs do not switch off by themselves once illuminated. You can manually reset the yellow LEDs by pressing the button on the card or remote display and holding it until the letters ‘rst’ appear on the 3-digit LED display.

Additional Information

Caution: Electrostatic discharge (ESD) can damage the motherboard, components, and the POST Cards. Always install components at an ESD-controlled workbench or with ESD-controlled tools, such as a properly grounded antistatic wrist strap. Inserting the card incorrectly will result in damage to the card and the system!
