8 General information
About PC test software DIFS16P 1.3
The DIFS16P PC (Diagnosis Inventory Feedback in Service 16 bit) diagnostic tool is a
SW-independent tool to check the PC hardware.
It is self booting from CD, and has its own operating system.
A "Burn-In Test" is possible.
Predefined test scripts are defined for a "Quick Test".
Test results are not intended to be stored on PC or other removable devices.
NOTE
The goal of the tests featured by this tool is to decide
whether to:
• Change single HW components
• Change the complete HW
• Reload SW on the existing HW
DIFS16P can be controlled by mouse or keyboard.
To navigate with the keyboard, use the arrow keys or the highlighted hotkeys which are
activated by the "Alt"-Key (in DIAGNOSIS Configure, for example: to set the level of a test
to level 2 use the combination Alt+2).
To switch between the navigation and the worktop use the left and right arrow keys.
Levels 0
The Test and Diagnosis Tool DIFS16P has 4 major characteristics.
¹ It provides information about the hardware inventory and it offers testing and
diagnosis functionality in different degrees of inspection.
¹ It offers a short, general test suite named "Level 1" to help you find out which
component is defective, checking basic functionality.
This level has a maximum duration of 5 minutes (hardware dependent).
¹ It offers another test suite named "Level 2," whose purpose is to test at a higher
degree of inspection.
This level is quality oriented and therefore takes more time.
¹ You can also choose "Level 3" in the "Configured Diagnosis," which tests at the
deepest level.
To run a test several times, you can specify "Cycles" in the "Configured Diagnosis" menu.

"Level 2" scans more deeply than “Level1” but is more time consuming.
DIFS then shows the result of the diagnosis with ECS-Code, the location of the error, and
additional details of the failure.
If a defect could not be found in “Level2”, you can also select a single test in the Diagnosis/Configure dialog (Fig.6/p.24). This test takes a minimum of one hour and can be set
to run repeatedly.

Evaluation of the results 5.3
If the DIFS tool detects a defective part that is available as a spare part, order the part and
verify the results.
If the DIFS tool detects a defective part that is not available as a spare part, order the
entire PC and verify the results.
After hardware repair, verification must be made by an additional diagnosis run on the
same level as that on which the error was found. The verification step must be made even
if the DIFS tool does not find an error or the tool could not be used in the diagnosis step.

Defective hard disk not detected by DIFS 0
Sometimes DIFS is not able to detect a defective hard disk. But you can check the hard
disks during the boot operation. Press the “Pause” button when the following screen is
shown (just an example).
Fig. 7: Defective hard disk
In this example, hard disks 1 to 3 (ID 0 to 2) are defective.
BIOSLOG-Errors 0
BIOSLOG-Errors are logged failures which have appeared in the past. These errors don’t
indicate an already existent problem. They only should be handled as a hint to the may
defective component.

To clear the BIOSLOG-Errors please go to the FreeDOSPrompt of the DIFS-Medium and
type “bioslog –clear”. Restart the PC and run DIFS again.
