5 Troubleshooting – Error Messages

If the Device Manager indicates a device conflict for the

desired I/O address, select another one. After shutting

down the computer, move the jumper on the Controller

to this address and then restart the computer.

Error message: “The configured interrupt cannot be used”.

Possible error source: The AVM ISDN-Controller A1

and another hardware component (e.g. a sound card) are

set to the same IRQ value.

Solution: Open the Device Manager (“Start / Settings /

Control Panel / System”) and select the AVM ISDN-

Controller A1. Click Properties and then on the

“Resources” page. Select “Interrupt Request” as the

resource type. Use the Change Setting button to set

the value to a free IRQ. Windows 95 automatically

displays any potential conflicts with other installed

hardware. To implement changes made here, Windows

95 must be restarted.

Error message: “A required .DLL file, CAPI*.DLL, was not

found.”

Possible error source: The DLL file (CAPI.DLL,

CAPI20.DLL or CAPI2032.DLL) has been renamed or

removed from the Windows\System directory.

Solution: Perform a complete new installation of the

AVM ISDN-Controller A1 to replace the missing files.

Error message: “Windows has finished detecting hard-

ware, but did not find any new devices on your system.”

Possible error source: The Add New Hardware Wizard’s

question “Do you want Windows to search for your new

hardware?” was answered with “Yes” during AVM ISDN-

Controller A1 installation.

Solution: Start the Add New Hardware Wizard again and

answer this question with “No”. Confirm by clicking

Next. See “Installation in Windows 95/98” in Chapter 3,

“Driver Software Installation”.
