Input/Output

Ports:

This

screen

allows

you

to

change

the

serial

and

parallel

port addresses. Mouse and keyboard information is also provided

on

this

screen.

The computer has one serial

port

and

one

parallel

port. Each port has a

special

address

(identifying

location)

assigned

to

it. If you add any additional

serial

or parallel port adapters, make sure that

each

port

has

a

different

address.

The

serial port

A

default

address

is

2F8-IRQ3.

The parallel port default address is 3BCh.

Other serial and parallel port addresses are available. However,

if

you

change

an

address

on

this

screen,

you

might

also

need

to

make

changes

to

the software. For instructions on changing the software,

see

the

user’s

guide

or

online

information

supplied

with

the

software.

The

Parallel Port

Mode

allows

you

to

change

the

mode

of

the

parallel

port.

The standard mode for the parallel port is the

Compatible

mode. You

can

increase the efficiency of the parallel port by using

Enhanced

modes

with

supporting

hardware.

Note:

The

Enhanced modes use

recent

technology

and

are

only

supported

by

newer

hardware

(such

as

a

printer).

If you change the mode of the parallel port, you might need to make changes to the supported hardware and its software.
