The “Performing Self Test...failed” message indicates one of the

following problems and possible solutions:

Problem Solution

An addressing conflict between

the TMB250.SYS Card Socket

Module address and another I/O-

addressed component of the

system has occurred.

The I/O address set you during

software installation does not

match the jumper configuration.

Run CTALKID. (See the Run

CTALKID section later in this

chapter for how to use this utility.)

CTALKID displays the jumper

address set on the ISA Bus Board.

If necessary, find an unused I/O

address.

Turn the computer off, open the

chassis, remove the ISA Bus

Board, and change the jumper

setting.

Reassemble the computer, turn the

power on and modify the

TMB250.SYS /IO option by

editing your CONFIG.SYS file to

read:

TMB250.SYS /IO:nnn

where:

nnn

is the I/O base address of the

switch setting.

Once you’ve modified the

CONFIG.SYS file, restart the

computer for the change to take

effect.

The product is malfunctioning. If, after running CTALKID and

verifying the jumper setting the

configuration still will not pass

the self test, call The

Manufacturer Technical Support.
