Using the System Setup Program: Dell Latitude CP
Infrared Data Port allows you to avoid resource conflicts by remapping the address of the
infrared ports or disabling the port. The COM1, COM2, COM3, and COM4 settings allow you to
take advantage of the computer's Fast IR support.
Settings for this option are:
● Disabled - Disables the infrared data port and makes the DMA, IRQ, and I/O resources
available for another serial device to use
● COM1 - Maps the infrared data port to COM1
● COM2 - Maps the infrared data port to COM2
● COM3 (the default) - Maps the infrared data port to COM3
● COM4 - Maps the infrared data port to COM4
For a change in the Infrared Data Port option to take effect, you must reboot your computer.
Infrared Mode
The Infrared Mode option appears on the screen only after an address is assigned in the
Infrared Data Port option. Infrared Mode lets you select Fast IR mode or Slow IR mode for use
with an infrared device. Select Slow IR if the Parallel Mode option is set to ECP and the Audio
Mode option is set to Full Duplex.
NOTES: The System Setup program limits the options available for Infrared Mode,
depending on how the Parallel Mode and Audio Mode options are set. If Parallel
Mode is set to ECP and Audio Mode is set to Full Duplex, the Infrared Mode option
cannot be set to Fast IR. This limitation is based on the number of available 8-bit
direct-memory access (DMA) channels.
The value selected for Infrared Mode determines the boot configuration for the
device. If Windows 95 finds other available resources, the operating system may
upgrade the configuration.
IntelliSpin
IntelliSpin lets you compensate for unbalanced or warped 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 automatically lowers its
