Dell Latitude CSx H - Manual (Page 81)

Docking IRQ tells the computer which interrupt request (IRQ) to assign to the docking station or replicator during the boot sequence. If Docking
IRQ is set to Optimized, the docking station or replicator is assigned a dedicated IRQ during the boot sequence. Select IRQ11 if a peripheral
device requires the use of the dedicated IRQ.
Docking Status
Docking Status shows whether the computer is attached to a Dell Latitude C/Port Family APR or C/Dock Family Expansion Station. No user-
selectable settings are available for this option.
External Hot Key
External Hot Key lets you use the key on the external keyboard the same way you use the key on the computer's keyboard.
Set this option to Scroll Lock (the default) if you are using an external keyboard. Set this option to Not Installed to disable this function on the
external keyboard.
External Media Bay
External Media Bay identifies the type of device —Diskette Drive, CD-ROM Drive, DVD-ROM Drive, or LS-120 Disk Drive—installed in the
external media bay. If the external media bay does not contain a device or is not attached, this option reads Not Installed. No user-selectable
settings are available for this option.
Infrared Data Port
Infrared Data Port is available only when the computer is docked; otherwise, this option is blue or dimmed. This option allows you to avoid
resource conflicts by disabling or remapping the address of the infrared port on the Dell Latitude C/Port Family APR or C/Dock Family Expansion
Station. The COM1, COM2, COM3, and COM4 settings allow you to take advantage of the computer's infrared support.
Settings for this option are:
l
Disabled — Disables the infrared data port and makes the direct memory access (DMA), IRQ, and I/O resources available for another serial
device to use
l
COM1 — Maps the infrared data port to COM1
l
COM2 — Maps the infrared data port to COM2
l COM3 (the default) — Maps the infrared data port to COM3
l COM4 — Maps the infrared data port to COM4
For a change to Infrared Data Port to take effect, you must reboot your computer.
Infrared Mode
Infrared Mode is visible only when the computer is docked and Infrared Data Port is enabled. Infrared Mode manages the infrared resources of
the computer and the external devices you use with it. This option lets you select Fast IR (the default) or Slow IR to use with an infrared device.
For a change to Infrared Mode to take effect, you must reboot your computer.
Internal Cache
Internal Cache displays the amount of internal cache your computer has. No user-selectable settings are available for this option.
Keyboard Click
Keyboard Click lets you choose whether the computer's keyboard makes audible clicking sounds. Click Volume must be enabled for Keyboard
Click to function. The volume of the simulated key clicks is controlled by the Click Volume setting.
Settings for this option are Disabled (the default) and Enabled.
