ENABLED

indicates that the computer detects a PC

Card in the PC Card connector and that power is
available to the connector.

DISABLED

indicates that the computer detects a PC

Card in the PC Card connector but no power is avail-
able to the connector. Use this setting to save battery
power if you are not using a PC Card that is installed
in your computer.

NOTES: A PC Card socket option must be set to

ENABLED

if

you want to use a PC Card in that connector.

You can set this option to

ENABLED

or

DISABLED

only if

a PC Card is installed in the socket.

A change to the

LOWER PC CARD SOCKET

or

UPPER PC

CARD SOCKET

option takes effect immediately (rebooting is

not required).

Microprocessor

MICROPROCESSOR

displays the type and speed of the

microprocessor installed on your computer’s system
board. There are no user-selectable settings for this
option.

Monitor Toggle

MONITOR TOGGLE

enables and disables the <

FN

><

F8

>

key combination that sends the video image to your com-
puter’s display, to an external monitor, or to both displays
simultaneously. (If you are using an external keyboard,
this option enables the <

CTRL

><

ALT

><

F8

> key combina-

tion from an MS-DOS window.)

Set this option to

ENABLED

(the default) to enable the

<

FN

><

F8

> (or <

CTRL

><

ALT

><

F8

>) key combination; set this

option to

DISABLED

to disable the key combination. Disable

this key combination only if it conflicts with the same key
combination used in an application program.

A change to the

MONITOR TOGGLE

option takes effect

immediately (rebooting is not required).

Parallel Mode

PARALLEL MODE

controls whether the computer’s built-

in parallel port acts as a PS/2-compatible (bidirectional)
port, AT-compatible (unidirectional) port, Enhanced Par-
allel Port (EPP)-compatible port, or Extended
Capabilities Port (ECP)-compatible port.

Options for this option are:

BIDIRECTIONAL

(the default) puts the port in bidirec-

tional mode so that the data transfer rate can be
improved by bidirectional operation, such as with a
network parallel adapter.

NORMAL

puts the parallel port in output mode only

(unidirectional) and is used for most devices, such as
a parallel printer.

EPP

puts the port in EPP mode to take advantage of

the functionality of EPP devices. Consult the device
documentation to select the appropriate protocol
(EPP 1.9).

ECP

puts the port in ECP mode to take advantage of

the functionality of ECP devices. Consult the device
documentation to select the appropriate protocol;
consult your operating system documentation to
determine if the operating system supports ECP
mode.

NOTE: The EPP and ECP settings also work for most
software written for the AT (unidirectional) and PS/2
(bidirectional) modes. Options that use EPP or ECP
mode may come with special drivers that need to be
installed in order to use these modes.

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.

Power Management

POWER MANAGEMENT

allows you to enable or disable

power conservation features when you are using battery
or AC power.

If you want to use any of the time-out options while using
battery power, the

BATTERY

option must be set to

ENABLED

.

If you want to use the time-out options while using AC power,
the

AC

option must be set to

ENABLED

.

A change to the

POWER MANAGEMENT

option takes effect

immediately (rebooting is not required).
