IBM 28L2234 manual IBM 2X/4X/24X CD-ReWritable Internal IDE Option Kit

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)

GR

German

FR

French

SP

Spanish

IT

Italian

JP

Japanese

/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.
