5.2.5 Error Messages in MS-DOS

Error message: „ISDNLOAD: installation error, controller-

xx with I/O address <xxx> not found.“

Possible error source: The jumper position on the

Controller which determines the I/O address does not

correspond with the entry in the A1 Setup program, the

I/O address is used by another hardware component

(e.g. a sound card) or the hardware does not exist.

Solution: Check which I/O addresses are available in

your computer and set the jumper on the Controller

accordingly (see Chapter 4 “Technical Specifications”).

Then enter the new I/O address in the driver software

using the A1 Setup program. After making these

changes, load the Controller using the ibase.bat file.

Error message: “ISDNLOAD: installation error, interrupt

<xx> not available”.

Possible error source: The AVM ISDN-Controller A1

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

configured to the same interrupt.

Solution: Check which interrupts (IRQs) are available in

your computer using the MSD.EXE program (DOS

directory). Start the A1 Setup program and set another

interrupt. Then load the Controller using ibase.bat.
