Changing the OS/2 IDE adapter device driver

The following IDE device driver is available:

BASEDEV=IBM1S5ð6.ADD

(for ISA computers)

This

device

driver

controls

IDE hard

disk

drives

and

IDE

CD-ROM

drives.

At

the

OS/2

command

prompt,

type

help IBM1S5ð6 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.

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

computer

to

start

audio

CD

software as

soon

as a

CD

is inserted

into the CD-RW

drive.

The

DMA

parameter

improves

computer

performance by

having

the

computer DMA

controller

handle

moving

data from

the

CD

to

memory,

freeing

the

computer

microprocessor

to

perform

more

important

tasks.

For

example,

activating

DMA

might

make

movies

and

games

run

more

smoothly

because

the

microprocessor

will

be

allocating

more

processing

time

to

video.

Changing

the

Auto

Insert

Notify

and

DMA

parameters

To

change

these

parameter

settings

from

the

Windows

98

or

Windows
