User’s Guide 4-Bit 4-Digit Diagnostic Card PC Analyzer Version 3.
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.
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. 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.
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 BIOS IRDY OSC FRAME RST SYS DATA IOW 12V -12V 5V -5V 3V3 Motherboard Clock Signal. Should be on when power is supplied to the motherboard even without CPU. BIOS Read Signal.
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.
