The controller stopped working when an add-in adapter was installed.
q Make sure the cable is connected to the port from the onboard network controller.
q Make sure your PCI BIOS is current. Try the “PCI Installation Tips” below.
q Make sure the other adapter supports shared interrupts. Also, make sure your operating system
supports shared interrupts; OS/2

does not.
q Try reseating the add in adapter.
The add-in adapter stopped working without apparent cause.
q Try reseating the adapter first; then try a different slot if necessary.
q The network driver files may be corrupt or deleted. Delete and then reinstall the drivers.
q Run the diagnostics.
PCI Installation Tips
Some common PCI tips are listed here.
q Reserve interrupts (IRQs) and/or memory addresses specifically for ISA adapters. This
prevents PCI cards from trying to use the same settings ISA cards are using. Use the SSU to
keep track of ISA adapter resources.
q Certain drivers may require interrupts that are not shared with other PCI drivers. The SSU can
be used to adjust the interrupt numbers for PCI devices. For certain drivers, it may be
necessary to alter settings so that interrupts are not shared.
Problems with Application Software
If you have problems with application software, do the following:
q Verify that the software is properly configured for the system. See the software installation and
operation documentation for instructions on setting up and using the software.
q Try a different copy of the software to see if the problem is with the copy you are using.
q Make sure all cables are installed correctly.
q Verify that the server board jumpers are set correctly. See Chapter 5.
q If other software runs correctly on the system, contact your vendor about the failing software.
If the problem persists, contact the software vendor’s customer service representative for help.
Bootable CD-ROM Is Not Detected
Check the following:
q Is the BIOS set to allow the CD-ROM to be the first bootable device?
