Service manual

Using the System Setup Program: Dell Latitude CP
determine the correct mode to use, see the documentation that came with the device.
NOTE: The ECP settings also work for most software written for the AT
(unidirectional) and PS/2 (bidirectional or normal) modes. Devices that use ECP
mode may come with special drivers that need to be installed in order to use these
modes.
Setting Parallel Mode to Disabled disables the parallel port and its assigned LPT address,
freeing its interrupt for another device to use.
For a change in the Parallel Mode option to take effect, you must reboot your computer.
NOTES: The System Setup program limits the options available for Parallel Mode,
depending on how the Audio Mode and Infrared Mode options are set. If Audio Mode
is set to Full Duplex and Infrared Mode is set to Fast IR, the Parallel Mode option
cannot be set to ECP. This limitation is based on the number of available 8-bit direct-
memory access (DMA) channels.
The value selected for Parallel Mode determines the boot configuration for the
device. If Windows 95 finds other available resources, the operating system may
upgrade the configuration.
Pointing Device
Pointing Device enables and disables the computer's touch pad.
Settings for this option are:
● Touch Pad-PS/2 Mouse (the default)
● Serial Mouse - Disables the touch pad and allows you to use a mouse connected to the
serial connector on the I/O port
If you want to use a serial mouse, you must first set the Pointing Device option to Serial Mouse.
For a change in the Pointing Device option to take effect, you must reboot your computer.
Power Management
Power Management (Page 4 of the System Setup screens) allows you to enable or disable
power conservation features when the computer is being powered by a battery or AC power.
