Settings for this option are:

front of the computer to COM1.

maps the infrared data port on the back
of the computer to COM1.
•
COM2: FRONT
maps the infrared data port on the
front of the computer to COM2.

(the default) maps the infrared data
port on the front of the computer to COM3.

DISABLED
(the default) disables both infrared data
ports and their assigned COM addresses. Disabling
the ports makes the interrupts available for other
serial devices to use.
For a change in the
INFRARED DATA PORT
option to take
effect, you must reboot your computer.
NOTE: You can use only one infrared port at a time.
Integrated Trackball
INTEGRATED TRACKBALL
allows you to enable or disable
the computer’s integrated trackball.
Settings for this option are:
•
ENABLED
(the default) enables the integrated
trackball.
•
DISABLED
disables the integrated trackball. Use this
setting when you want to attach a serial mouse to the
computer.
If you attach a mouse to the Personal System/2 (PS/2)
keyboard/keypad/mouse connector, the computer auto-
matically detects and disables the
INTEGRATED
TRACKBALL
option (but does not change the actual
setting).
For a change in the
INTEGRATED TRACKBALL
option to
take effect, you must reboot your computer.
IntelliSpin
INTELLISPIN
lets you compensate for unbalanced CDs,
which can cause the computer to vibrate when the
CD-ROM drive is in use. This option allows you to use
discs that might otherwise be unreadable. This option is
available for CD-ROM drives with speeds of 6X or higher.
If this option is set to
HIGH PERFORMANCE
(the default),
the CD-ROM drive always runs at the highest speed. If
this option is set to
VARIABLE
, the CD-ROM drive auto-
matically lowers its speed to reduce or stop the vibration
caused by the unbalanced CD.
NOTE: When this option is set to
VARIABLE
, the
CD-ROM drive takes several seconds to determine the
proper speed. You cannot access the disc during that
time.
Internal Hard Drive
INTERNAL HARD DRIVE
displays the capacity of your
computer’s hard-disk drive. This option does not have
any user-selectable settings.
Keyboard Click
KEYBOARD CLICK
lets you choose whether the built-in
keyboard makes audible clicking sounds. The
SPEAKER
VOLUME
option must be enabled for this option to func-
tion. The volume of the simulated key clicks is the same
as the setting in the
SPEAKER VOLUME
option.
Settings for this option are
DISABLED
(the default) and
ENABLED
.
A change to the
KEYBOARD CLICK
option takes effect
immediately (rebooting is not required).
Lower PC Card Socket and Upper PC Card
Socket
LOWER PC CARD SOCKET
and
UPPER PC CARD SOCKET
indicate the status of the PC Card connectors in your
computer.
The possible settings for each option are:
•
NOT INSTALLED
indicates that the computer does not
detect a PC Card in the PC Card connector or that a
PC Card is not properly installed in the connector.
