NOTES: Some external devices require you to load software called device drivers into system memory before using the devices. These
device drivers help your computer recognize the external device and direct its operation. Instructions for installing this software are
usually included in the upgrade kits.
The APR provides the same I/O connectors as your computer and, in addition, provides a serial port and one additional PS/2 port. For
more information on the APR, see the documentation that came with it.
