1 User's Guide 4-Bit 4-Digit Diagnostic card PC Analyzer Version Advanced User's Guide Model: postcard_32. For use only in a desktop model computer with PCI or ISA slot 1. User's Guide INTRODUCTION. Diagnostic card is a powerful Diagnostic tool for technicians and administrators to troubleshoot various problems of IBM compatible PCs. It is easy to install, yet extremely powerful to use. With Diagnostic card in hand, you no longer have to go through tedious and time consuming process of trying to figure out what is wrong with your PC hardware. Diagnostic card will tell you exactly what is wrong with your PC in just seconds. It saves you time and money.
2 Our new and improved design of Diagnostic card can work with almost all popular types of CPUs, Motherboards, and BIOS. All though we try, it is not possible to update this manual every time a new motherboard is made by the manufactures. It is always advised to visit the bios manufacture website, and download the latest codes per bios revision. Or visit for an online reference. System Requirements The Diagnostic card itself only requires an empty PCI or ISA expansion slot. It is not necessary to install memory chips to perform analysis. POST Codes can be displayed through the hexadecimal display panel on the Diagnostic card itself. Tech Support Tech Support 1-888-359-0747.
3 Diagnostic card INDICATORS. Two Indicators' are any light emitting diodes (LED) or hexadecimal display panel that may be mounted on an Diagnostic card . This section discusses the following indicators that appear on the Diagnostic card : POST Code Display PCI BUS SIGNALS LEDs POST Code Display The POST Code Display is made up of a dual, dot matrix hexadecimal read-out that displays Power On Self Test (POST) status codes. 2. User's Guide The Feature of 4-Bit 4-Digit PC Analyzer This card can work on either PCI or ISA Slot Manually to keep on track for the post code in sequence Forward and backward button (S1,S2) Design, it can be easy to check the post code step by step.
4 Remote LED display and button, it is suitable for mounting outside the casing Self-Checking Remote Display Function User Guide 1. Insert the post code card in PCI or ISA slot. Power on the machine. The post code will show on display. The left Post code display monitor the real time and right post code is for previous one. After the machine booting up complete, press S1 button about 2 seconds, then it can be checked the previous post code by pressing S1 or S2 button. 2. If S1 button is pressed 2 more seconds, it shows the testing speed rate which represents the PCI clock frequency. For example, if the display show F-33, which represent PCI clock 33 MHz.
5 3. If S1 button is pressed 2 more seconds for next stage, it has self-checking function from 0000 to 9999. To return original status is just by pressing S1 button again. Remote Display Cable Remote LED displays LED Light Current Post Code Previous Post Code S1. S2. Speaker 3. User's Guide Power On Self-Test (POST) Codes Most AT and 386 computers (and a few XT computers) output status codes during POST. The Diagnostic card displays these codes during and after POST. Refer to Appendix A for a comprehensive listing of POST codes provided by BIOS manufacturers. PCI Signal Definition: CLK Motherboard Clock Signal. Should be on when power is supplied to the motherboard even without CPU.
6 BIOS BIOS Read Signal. Flashes when CPU reads BIOS code. IRDY Device Ready. Flashes when an IRDY signal is detected. OSC ISA Oscillation Indicator. Indicate ISA Oscillation Signal is available. FRAME PCI Bus Frame. Should be on under normal circumstances and flashes when a PCI Frame Signal is detected. RST Reset. After power on or reset, this indicator should be on for an half second and then turned off. SYS Bus pulse. If the LED blinks, the main board bus is running. If the bus is not running, the LED is off. DATA Data Transfer. This signal shows that a device has been selected for data transfer. If no blink, the bus controller could be faulty.
7 IOW I/O Write. Lights when the BIOS writes to device and provides the same troubleshooting clues as the I/O READ. 12V Power Supply, 12-Volt Positive. Should be on all the time otherwise there is a short circuit. -12V Power Supply, 12-Volt Negative. Should be on all the time otherwise there is a short circuit. 5V Power Supply, 5-Volt Positive. Should be on all the time otherwise there is a short circuit. -5V Power Supply, 5-Volt Negative. Should be on all the time otherwise there is a short circuit. 3V3 Power Supply, Some motherboards have power supply to PCI slots. This indicator should be on if the motherboard supplies power. INSTALLING the Diagnostic card Installation Procedure TO INSTALL A Diagnostic card : 1) Install the Diagnostic card in any available PCI or ISA expansion slot.
8 2) Power on the machine. 3) Install JP2 External Speaker Connection if required, see note below. 4) Observe POST CODE. 4. User's Guide POST Codes When the machine is turned on, the hexadecimal display should show the various POST codes as the system executes (unless it has a rare BIOS that does not display POST codes). If the machine does not boot, system POST has detected a fatal fault and stopped. The number showing in the hexadecimal display on the Diagnostic card is the number of the test in which POST failed. Refer to Appendix A for a listing of POST codes. Troubleshooting During POST. After initial power up, Power-On Self-Test (POST) codes begin displaying on the Diagnostic card 's hexadecimal displays (for most machines).
9 NOTE: A few machines use the parallel port to display POST codes instead of the Diagnostic card . THE POST PROCESS. The ROM built onto the motherboard of the computer rums its built-in POST (Power-On Self-Test). when you switch power on to the computer, press the reset button on the computer, or press Ctrl-Alt-Del (warm boot). POST performs a tightly interwoven initialization and testing process for each of these methods, but it typically does not test or initialize memory above 64K for warm boot. You can get an even better idea of the detailed process by studying the POST code listings in Appendix A. JP2 EXTERNAL SPEAKER CONNECTION. On some older motherboards you may encounter no onboard speaker or non functional motherboard speakers.
10 Use the 2-pin gray jumper wire included to jump the connection from the speaker terminals on the motherboard header to the JP2 jumper on the PC POST card . This will connect the onboard speaker of the PC POST card so you can hear BEEP CODES as well as see POST CODES. 5. Appendix A. Error Code-00. AMI (00)Going to give control to INT 19H boot loader.
