Optional Devices
This section provides information on solving problems related to optional devices.
Note: Make sure the MX1 is powered on before you turn on any powered optional devices.
To help determine which device is causing the problem:
• Check that all connecting cables are correctly and firmly attached. Loose cables can
cause erroneous or intermittent signals. You may need to inspect connecting cables for
loose wires, and check connectors for loose pins.
• Isolate the problem. Turn the computer off and remove all devices. Turn the computer on
and write down any error messages.
• Turn the computer off. Add one optional device and turn the computer on again.
Continue this procedure of adding one device at a time until you resolve the problem.
• Device Configuration. The smooth operation of the system depends on the interaction of
all devices, programs and features.
Note: Before you make any changes to your configuration files, make a copy of each file
(typically with a different extension, for example, copy AUTOEXEC.BAT to
AUTOEXEC.OLD). After you modify the configuration files, restart the computer for the
changes to take effect.
The following table provides some solutions to common configuration problems:
Problem Solution
You connected a device
and the device isn’t
operating properly.
If you start programs or drivers from the configuration files
(CONFIG.SYS and AUTOEXEC.BAT), remove the
commands that start those programs from the configuration
files and restart the computer.
Add the program commands back into the configuration files
one at a time until the problem reappears. Experiment with the
order of the programs. (Keep in mind that some files must be
loaded prior to others in order for your system to operate
properly. Check the software documentation for any
configuration requirements.)
You connected an external
device and the computer
isn’t operating properly.
Make sure you chose the correct setting for the device in the
BIOS Setup utility.
You may have plugged in a device when the MX1 was on.
Turn the MX1 off, reconnect the device and turn the MX1 on
again.
The cable wiring may be faulty. Try a different cable or check
the device’s wiring requirements. Check all the connections.
Try operating the system again.
