In Bi-directional mode, 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.

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