Installation and Maintenance Problems

Installation problems are most likely to appear after you have added
a new drive or other hardware item to the system. If you have a
problem after installing additional hardware, xemove the new item
and see if the problem disappears. Hit does, you know the problem
is in that item or its installation. Repeat the installation, following
the hardware manufacturer's installation instructions carefully.
If you have several expansion devices, the problem may be an
interaction between two or more items that by themselves work
properly. Try running your system with different combinations of
expansion devices to isolate the offending items. If the item
requires its own software, consider different settings the software
may offer.
