Replacing the motherboard
Follow the procedures in this section to replace the motherboard. Failure to follow the
instructions in this section may corrupt the system (not easily repaired in the field) or result in
an incomplete installation (see
).
Troubleshooting cautions
• Before deciding to install a new motherboard, consult
.
• Inspect all cables and internal components as described on pages
. If these
inspections do not solve the problem, locate symptoms in the troubleshooting table

motherboard is faulty, always troubleshoot in the following order:
(Troubleshooting in the wrong order will cause the system to malfunction. In general, it is
highly unlikely that both a HDD and the motherboard are defective; therefore, avoid
replacing both to solve one problem.)
–
First, replace the HDD and install system software.
Always replace a faulty HDD with a new HDD. Transferring a HDD from one E-8100
to another is incorrect and strongly discouraged.
–
If the problem persists, reinstall the original HDD in the system, and then replace the
motherboard.
Motherboard cautions
If you have exhausted all other troubleshooting remedies and determined that you need to

the new motherboard.
•
Do not
transfer the BIOS chip from the old motherboard onto the new motherboard.
BIOS chips are not interchangeable.
• Do not reinstall system software at this time.
Reinstalling system and user software is not necessary when installing a new motherboard
and can result in an error if done before updating the system with the one-time use dongle
and the Feature Update CD (described on
