IDE

adapter

device

driver

The following

IDE

device

driver

is

available:

BASEDEV=IBM1S5 6.ADD

This

device

driver

(available

for

ISA

computers)

controls

IDE

hard

disk

drives

and

IDE

CD-ROM

drives.

From

the

OS/2

command

prompt,

type

help IBM1S5 6

to see

the

optional

parameters

that

are

available

for

ISA

computers.

Special

parameters

are

required

if

your

computer

has

an

IDE

controller

that

does

not

use

a

standard

interrupt. Check

the

/A

and

/IRQ

parameters

in

the OS/2

help

utility.

For

IBM

Micro

Channel

computers,

an

IDE

device

driver

is

available

on

the

IBM

Web

site. Use the Web site

search

feature,

and

look forIBM2IDE.ADD.

Changing

the

Windows

98

and

Windows

95

device

drivers

Windows

98

and

Windows

95

have

two

device

driver

configuration

parameters:

Auto

Insert

Notify

and

DMA.

The

Auto

Insert

Notify

parameter

enables

the

system

to

start audio

CD

software

as

soon

as

a

CD

is

inserted

into

the

CD-ROM

drive.

The

DMA

parameter

improves

system

performance by

having

the

system

DMA

controller

take

responsibility

for moving

data

from

the

CD

to

memory,

freeing

the

system

CPU

to

perform

more

important

tasks. For

example,

activating

DMA

might

make

movies and games run more

smoothly

because

the

CPU

will

have

more

time

to

concentrate

on

video.

To

change

these

parameter

settings

from

the

Windows

95

or

Windows

98

desktop:
