4 Connecting and Installing Optional Devices

In Bi-directionalmode, the parallel port allows both data input and output only.

In ECP mode, the parallel port uses Direct Memory Access (DMA) to transfer data in the background without using CPU resources. The parallel port operates in ECP mode when you load an Extended Capabilities Port device driver. Only ECP-aware peripherals support this mode. If you configure the Operation Mode option field in the BIOS Setup program as ECP, the application you are using must be ECP aware.

See “Advanced Menu” beginning on page 91 for more information on setting the printer operation mode.

Connecting an External Pointing Device

You can attach an external pointing device such as a mouse or a graphics tablet to either the PS/2 port or the serial port. Refer to your pointing device’s documentation for information on which port to select.

Follow these instructions to connect an external pointing device:

1.Determine the type of interface (PS/2 or serial) required by your pointing device. Refer to the device’s operating manual for more information.

2.If the device requires a PS/2 interface, locate the external mouse (Mini-DIN) port at the rear of the laptop. Refer to Figure 3 on page 7. Connect the male connector of your device cable to the female PS/2 port on your laptop. If the device requires a serial interface, locate the 9-pin connector at the rear of your laptop by opening the large panel. Refer to Figure 3 on page 7. Connect the 9- pin female connector of your device cable to the 9-pin male serial port on your laptop.

When connecting a serial mouse, the system may require additional configuration activities or may ask you to reboot your system.
