CrossBrand - Parallel Port Operations on IML Systems
Applicable to: World-Wide
Symptom:
The parallel port may be inoperative when running OS/2, or other operating systems which take advantage of the DMA (Direct Memory Access) interrupt capability of the hardware.This may be experienced with customer devices (ie security device, voltage sensing devices) and on some printer operations. Diagnostics and other print operations function correctly.
Problem Isolation Aids:
None
Fix:
This is not a hardware failure. The following procedure will correct the problem.
The parallel port arbitration level must be set to "Disabled", by using the following procedure:
a. IML (Initial Micocode Load) the system partition.
b. At the main menu, select "Set Configuration"
c. At the "Set Configuration" menu, select "Change Config".
d. Using the keyboard arrow key, move the selector bar to "Parallel Port Arbitration Level" (Arb Level) under the "Built in Features" heading.
e. Using the F6 key, toggle through the selections until "Disabled" is visible.
f. Save the changes using the F10 key. Press "Enter" then "Exit", and follow instructions on the screen.
The configuration change will become effective on the next IML.
Note:
The change in configuration should also be saved on the customer's back-up reference diskette.
