The

device

driver

automatically

checks

the

industry

standard

primary

IDE

port

(address

1F0,

interrupt

14)

and

secondary IDE

port

(address

170,

interrupt

15).

The/P

parameter

is

not

needed

 

if

 

your

CD-ROM drive is

 

connected

to

either

of

these

ports.

However,

if

 

your

computer

(or IDE

adapter)

uses

different

 

IDE

port

addresses

or

 

interrupts,

you

must use this

option.

Refer

to

the

instructions

that

come

with

your

computer

or

IDE

 

adapter

for

 

more

information about

the

configuration

of

your

computer

or

adapter.

 

 

 

 

 

 

 

 

 

 

xxx

is

 

the

base

 

address

of

 

the

IDE

port.

 

 

 

 

1F0

 

for

the

primary

 

IDE

port

(Port

1)

 

 

 

 

170

 

for

the

secondary

IDE

port

(Port 2)

 

 

 

yy is the interrupt (IRQ) level.

14

for

the

primary

IDE port

(Port 1)

15

or

10

for the

secondary

IDE port (Port 2)

/U: n

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This

parameter

specifies

if

your

computer

initializes

with

the

CD tray

unlocked

or

locked.

/U:0

initializes

with

the

tray

unlocked

 

.

/U:1

initializes

with

the

lockedtray .

The

default

command

is

 

n =0.

This

command

might be

used

if

you

want to

secure

your

CD

in

the

drive.

 

 

 

 

 

 

 

/L: xx

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This

parameter

specifies the message language where

 

xx

designates

the

language.

 

 

 

 

 

 

 

 

 

 

US

 

English

(default,

does

not

need

to

be

specified)

/T:n

When four drives are connected, for example, the syntax in the CONFIG.SYS file would be:

DEVICE=C:IBMIDECD.SYS /D:IBMCD1

/P:1F ,14

 

 

/P:17 ,15 /P:1E ,12 /P:16 ,1

 

 

(Do

not

truncate

the

actual

device

driver

entry.

Place

the

complete

DEVICE=

on

one

line

in

 

the

CONFIG.SYS

file.)

 

/A:n

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This

parameter

specifies

the

audio

play

mode.

For

a

stereo

CD,

you

can

type

/A:0

or

/A:1.

For

a

monaural

CD

(left

or right

channel

 

only),

type

/A:1

in

order

to

play

the

monaural

audio

signal

 

from

the

right

and

left

 

channels.

The

default

is n =0.

This

 

parameter

specifies

time delays

to

be

built

into

the

IDE

read

loop.

Use

 

this

parameter

only

in

computers

that

do

not

support

the

IOCHRDY

signal

on

the

IDE

bus,

and

in

computers

that

 

read

from

 

the

IDE port

faster than the CD-ROM

can

 

provide

data.

This

parameter

is

usually

not

required

in

most

computers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

n

is

a

relative

timing

parameter

that

depends

on

processor

speed.

When

the

value

of

n

increases,

the

 

drive data-transfer

rate

 

decreases.

Valid

 

values

for

n

are

0

through

99. The

default

for

n

 

is

0,

and

the

/T

parameter

is

not

required.
