User manual

⑥ KLPI4 and KLPI6 can be plugged in PCI, ISA and LPT ports. Their test mode

supports kinds of interfaces.

2) There are beep warning functions for KPI4, KPI6, KLP4 and KLP6.

3) KPI4 and KPI6 plugged incorrectly, no component will be burnt out.

4) By KPI4, KPI6, KM4 or KM6, the important signals of mainboard can be tested

even without CPU, memory and video card.

5) KL4 and KL6 are USB-powered. Not plugged in the parallel port, KL4 or KL6

will not show codes no matter it is powered, which won’t mislead the users.

6) External Display. You can see the failure codes from outside.

5. Operation Flow

1. Shut down the power and take out all extended cards. Plug the PC Diagnostic

Card in ISA slot (Note: The front side of the component on ISA slot should face the

power supply, otherwise neither PC Diagnostic Card nor the mainboard will work

though they won’t be burnt out), PCI slot, MiniPCI slot or parallel port (LPT). (Note:

When using KL4, KL6, KLP4 or KLP6, plug the card into the parallel port first, then

connect the USB line, finally start up the computer.)

2. The PC Diagnostic Card starts running and the LED shows the codes. The user

may determine the testing result with POST Code Table (except extended

equipments ).

3. If the result shows failure, please shut down the power and solve the problem

according to the POST Code Table. And repeat from step 2.

4. If the result shows normal, please shut down the power and plug in the video

card, I/O card, keyboard, hard drives and extended cards, and restart up the

computer.

5. The PC Diagnostic Card will start running again and the LED shows the codes.

Determine the test result again with POST Code Table (It shows the working

status of all hardware this time).

6. If the result shows failure, please shut down the power again and solve the

problem according to the POST Code Table. And then repeat from step 2.

7. The test result shows normal, but the operating system can not boot, then the

hitch may lie somewhere of software, disk drive, disk controller or DMA circuit.

Please make relative treatment.
