The

/P

parameter

 

is

not

needed

if

your

CD-ROM

drive

is

on

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

to

 

understand

how

your

computer

or

 

adapter

is

configured.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

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)

 

 

 

 

 

 

As

an

example, when four drives have been

connected,

 

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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Specifies

the

audio

 

play

mode.

For

a

stereo

CD,

/A:0

or /A:1

is

acceptable.

For

a

monaural

CD

 

(left

 

or

 

right

channel

 

only),

/A:1

will

play

the

monaural

 

audio

signal

from

both

the

right

and

left

 

channels.

The

default

is

n =0.

 

 

/U: n

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Initialize

with

the

tray

 

locked

or

unlocked.

/U:0

is unlock

.

/U:1

lockis

. The

 

default is

n =0.

This

command

might

be

used

 

if

you

wish

to

secure

your

CD

in

the

drive.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

/L: xx

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Specifies

the

message

language

 

where

 

 

xx

 

designates

 

the

language.

 

 

 

 

US English (default, does not need to be specified)

 

 

GR

 

German

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

FR

 

French

/T:n

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Initializes

with

time delays

built

 

into

the

IDE

 

read

loop.

Use

this

parameter

only

 

in

computers

 

that

do not

support

the

IOCHRDY

signal on

the

IDE

bus,

and

that

read

from

the

IDE

port

faster

than

the CD-ROM can

provide

data.

 

This

 

is

a

very

uncommon

situation

and normally

this

parameter

is

not

required

in

most

computers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

n

is

a

relative

timing

parameter

 

that

depends

on

processor

speed.

The

larger

the

value

 

of

n ,

the

 

slower

the

drive

will

transfer

data. Valid

values n forare

0

through

99.

The

default

for

n

is

0,

and

the

 

/T

parameter

is

not

required.
