CDSETUP

will

set

this

value to

10.

The

default

value for

MSCDEX

with no

/M

parameter

is

4.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The

greater

this

value,

the

better

the

 

CD-ROM

drive

will

perform.

However,

each

buffer

uses

about

 

2 KB

of

memory,

 

and

specifying

too

many

buffers

might

slow

down

your

computer

or

interfere

with

 

other

programs

that

have

large

 

memory-usage

requirements.

Using

expanded

memory

 

(see

the

/E

option

 

in this

section)

or

loading MSCDEX.EXE

into

 

high

memory

(refer

to

your

 

DOS

user

 

manual

or

 

memory

manager

 

user

manual)

 

might

 

allow

you

to

specify

 

a

larger

 

number

of

 

buffers

to

enhance

CD-ROM

performance

 

without

adversely

 

 

 

 

affecting

programs

that

 

have

large

memory-usage

requirements.

 

 

 

 

 

/E

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Instructs

the computer to use expanded memory, if available. For example:

 

 

C:\MSCDEX.EXE /D:IBMCD1

 

/E

 

 

 

 

 

 

 

 

Note

that

you

must

first

load

an

expanded

memory

device

driver

before

using

this

option.

If

no

expanded-memory

device

driver

is

loaded,

the

 

following

error

message

appears:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Expanded Memory not present or not usable.

/V

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Instructs

the

computer

to

display

a summary

of

RAM

allocation

and

expanded

 

 

memory

usage

 

at

startup

 

time.

 

 

 

 

 

 

 

 

 

 

 

 

/L: driveletter

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Specifies

the

drive

letter

to

be

assigned

to

 

the first CD-ROM

drive.

Do

not

assign

a

letter

already

 

used

by

an

existing

 

drive

or

your

computer

will

be unable

to access the CD-ROM drive. For example, you might use:

 

 

 

 

 

C:\MSCDEX.EXE /D:IBMCD1

 

/L:F

 

 

 

 

 

 

 

Normally,

the

CD-ROM

drive

is

assigned

to

the

next

available

drive

letter

after

devices

such

as

diskette

drives

and

hard

disk

drives. Therefore,

use

this

option

only if

you

wish

to

assign

a

drive

letter

 

beyond

the

last

letter

previously

assigned

by

DOS.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

/K

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Instructs

MSCDEX.EXE

to

 

use

Kanji

(Japanese)

file structures,

if

present,

 

rather

than

the

default

alphanumeric

file

structures.

 

 

 

 

 

 

 

/S

Instructs MSCDEX.EXE to allow sharing of CD-ROM drives on networked computers.
