four-digit Kingnostic Card. It shows a 2 digit code for each press. And it goes back
to show “no” at the sixth press, and the last code that the test stopped at the
seventh press. For example: If the LED shows D0, D1, D2, D3, D4, D5, D6, D7, D8,
D9, Da, Db and stops at DC during testing, it will show Db for the first press, and
Da the second press, …D7 the fifth press, and “no” the sixth press. And it goes
back to DC for the seven press, as below:

8. The KL4, KLP4, KL6 and KLP6 with parallel pots are applicable to the
laptops and desktops with LPT. The failures can be found without opening the
computer cases.

The USB line is used for power supply only. So the user have connect the
parallel port with LPT, and then connect the USB of the PC Diagnostic Card and the
USB of the computer with the USB line attached, finally turn on the PC and check
the failure codes.

Note: Nowadays, most computers made in mainland and Taiwan use
AMIBIOS and PHOENIXBIOS mainboard, and they can be tested with PC
Diagnostic Cards that have parallel port. Other computers such as IBM, TOSHIBA,
HP, DELL and SONY usually PHOENIXBIOS or IntelBIOS, the ones that use
PHOENIXBIOS can be tested with PC diagnostic cards that have parallel port.

9. Time for the reset signals of ISA, PCI and LPT ports are different. Maybe
PCI card still shows “no” when ISA card start to show POST codes. And time to
show POST code for LPT port is also different with other interfaces such as PCI and
ISA, and the parallel port and other interfaces show different codes when the PC
works normally, because of different time sequence for PC managing different
interfaces. But the failure codes shown are the same no matter what type of
interface is used to in test.

10. The two digit and four digit PC Diagnostic Cards are not so mysterious as
you imagine. What they can do is just to display the POST codes that indicate the
failures (especially when the screen is blank). Some POST programs of BIOS stop
at the last code which the system fails to pass (failure code), while the others stop
at the last code which the system succeeds to pass (non failure code). With code
recheck functions, KPI4, KM4A, KL4 and KLP4 can show what codes the self test
has passed, from which the user can know what components work well. Both
functions and performances of two digit and four digit PC diagnostic card are not
better than those of KPI6, KM6, KL6 and KLP6. Because there is a wide range of
code collection, many versions and types of BIOS, varieties of content of POST
programs, new functions of BIOS, the meanings of codes may be not complete
and perfect. So the code meanings in this manual are only for your reference.
Please contact the mainboard manufacturers and BIOS makers for the most
accurate and latest POST code information.
