    1. The PC Analyzer is also named POST (Power On Self Test ) card.it could display the error code by the result of POST, then you would soon determine cause of the error by error codes table. Especially when the PC can't boot operating system, or it is a black screen, or the card and motherboard couldn't issue an audible beep. It is a powerful diagnostic tool. Now just use it, and you'll get twice the result with half the effort. When the power is turned on, the BIOS first would have a strict test with system circuit 、 memory 、 keyboard 、video 、 hard disc 、 floppy drive and so on. It analyzes the system configuration and initializes the base I/O setup. At last when all is normal, it boots the operating system .The obvious feature of testing crucial components is demarcated by curse's appearing .At first, the BIOS tests the crucial components .If the testing is abnormal, the computer stopped compulsively; The curse cannot appear in the screen; There is no response to the screen; If the test of crucial components is normal, the BIOS tests common components afterwards. If the testing of common components is abnormal,the computer continues to run and of error. When there is some trouble with the computer and the testing is abnormal, especially the testing crucial component, no displaying in the screen, the black screen, you can put the Post card in the expansive 
slot.You will know the cause of the trouble by the code that the card indicates and the error codes table of this manual.
      2. Pay attention to distinguishing "intiative code" and " trouble code". The intiative code is meaningless.Only can the trouble code point the cause of trouble with 
computer out.

      3. The error codes table is in the order of the codes' value from small to big. The sequence in which the code displays is decided by BIOS of the motherboard.
      4. The codes that haven't been defined is not included in the table.
      5. For the different BIOS (such as AMI 、 Award 、Phoenix ), the code is meaning differently . So you must make sure which type of BIOS you are testing by viewing the users' guide ?￠Seeing symbol on the BIOS IC of the motherboard or seeing the screen directly while the computer booting.
      6. There is no more than some code displayed when you insert the card into the PCI slot on a few brands of motherboards, but when you plug it into the ISA slot, all the code can be displayed. At present, it has be discovered that all codes is displayed when you insert the card into the PCI slot of several brands of computers which not all codes 
is displayed when you plug the card in the ISA slot. So we suggest that you need plug the card from one slot to another slot when consulting the code is unsuccessful.In 
addition, the different slot on the certain motherboard in the different states. For example, all codes can be displayed from "00" to "FF". when you plug the card in the PCI slot that is near the CPU on the motherboard DELL810 while only a part of codes can be displayed from "00" to "38" when you plug the card in the other PCI slot on the motherboard DELL810.
      7. The time of PCI that the resetting signal needs is not always synchronized with the time of ISA .So sometimes the code begin to be displayed when the card in the ISA, but the resetting light of PCI has not been off while the card stops to display the original code.
      8. As there are more and more different kinds and structures of the motherboard, and the codes of BIOS POST is updated constantly, so the cause of trouble that error code indicates is just a reference for you.
      9. According to experience, the card of two-bit code is reliable if you plug it in the slot on the motherboard below and including the P￠ò 300. It will stop running or it dose not indicate the error code or it indicates false error code. As until recently we haven't received the bad reflect about the four-bit code card of P0050. We suggest you buy and use the four-bit code card of P0050.

The explanation of testing the speed of PIC/ISA Bus
You can use the function of testing the speed of PIC/ISA Bus on certain Mainboard. It will display reference value of the speed of PCI/ISA bus. This will can help you suffer no losses when you buy the Main board or you sell the Main board at good price. 

Insert the PC Analyzer in the slot on the mainboard. Press and hold the function switch for about 0.8 second two times. It will display the decimal refrence value of the speed of bus after it displayed "2- - - "for about half a second. The value is larger, 
the speed of bus is more high. 
Alert:
When PI0050A is inserted in ISA slot, If BIOS LED is on, It indicates that BIOS is not being read from at the moment; If BIOS LED is off, It indicates BIOS is being read from at the moment. If BIOS LED sparkles, It indicates the time for which BIOS has been being read is short. Sometimes there are so short time that you cannot feel the BIOS LED have been on by naked eyes. If sometimes BIOS has not been being read for a short time, the time is so short that you cannot feel the BIOS LED have been off by naked eyes. The definition of "BIOS" LED of PI0050A is opposite of "BIOS" LED of two-bit-code PC Analyzer and PI0050.
When PI0050A is inserted in PCI slot, If FRAME LED is on, It indicates that there is cycle frame signal of PCI slot or MiniPCI slot at the moment; If FRAME LED is off, It indicates that there is no cycle frame signal of PCI slot or MiniPCI slot at the moment. If FRAME LED sparkles, It indicates that duration of cycle frame signal is short. Sometimes there is so short duration of cycle frame signal that you cannot feel the FRAME LED have been on by naked eyes. the same kind, if sometimes the cycle frame signal have vanished for a short time, the time is so short that you cannot feel the FRAME LED have been on by naked eyes.
