Parallel port mode

As long as the Parallel Port setting is not Disabled, this
option lets you choose an operational mode for the
parallel port.
You can choose either the Compatible mode or one of
the extended modes (ECP, EPP, or PS/2 Bidirectional) for
a parallel port. The parallel port extended modes will
increase the efficiency of your parallel port; however, the
extended modes use recent technology and are only
supported by newer hardware (such as some printer
models). The available extended modes are:
•
PS/2 Bidirectional
This mode is used for data transfer to other PC
systems and supported devices.
•
ECP
The Extended Capabilities Port mode (ECP) provides
higher speed data transfers than the Compatible
mode. It is used for high-speed printers and other
devices.
•
ECP and EPP 1.7
This mode combines the capabilities of the
Extended Capabilities Port (ECP) and Enhanced
Parallel Port (EPP) modes. This mode is not
compatible with the ECP and EPP 1.9 mode.

•
ECP and EPP 1.9
This mode combines the capabilities of the
Extended Capabilities Port (ECP) and Enhanced
Parallel Port (EPP) modes. This mode is not
compatible with the ECP and EPP 1.7 mode.
If you change the mode of a parallel port on an adapter
card, you might need to make changes to the port's
adapter card and its software. See the user's guide or
online information that came with the adapter card.

Mouse

This option shows if a mouse is installed.

Keyboard NumLock state

This option displays whether the NumLock function on
the keyboard turns on automatically each time you turn
your computer on. You can change this setting to On or
Off.

Keyboard speed

This option displays the speed at which your keyboard
responds when you hold down a key. The Normal rate is
10 characters per second. The Fast rate is 30 characters
per second. You can select the speed that is most
comfortable to you.
For example, if your keyboard speed is set for the Fast
rate and you hold down one of the arrow keys, the
