CDS-420/940E/620/621 MANUAL INSTALLATION
You may also manually install the Portable Multimedia Kit device driver if the default setting conflicts
with your system.
1.
Copy the files EXPCDM.EXE from the Portable Multimedia Kit device driver disk to your hard disk.
2.
Add “
LASTDRIVE=Z
” to the TOP of your CONFIG.SYS file. If you already have a LASTDRIVE line
with a letter other than Z, change it to Z.
3.
If you wish to use the CD-ROM only, add the following lines near the BOTTOM of your CONFIG.SYS
file:
DEVICE
=
drive:\path
\EXPCDM.EXE /P:320 /D:MSCD001
If you want to enable both the CD-ROM and the Sound, add the following lines instead of the above:
DEVICE
=
drive:\path
\EXPCDM.EXE /P:220 /I:10 /S /D:MSCD001
where
drive:\path
specifies the directory containing the files EXPCDM.EXE
If your CONFIG.SYS file is already loaded with PCMCIA software, such as SystemSoft’s CardSoft or
Databook’s Cardtalk, it is necessary to add the above lines AFTER the PCMCIA software. Otherwise,
the PCMCIA interface card will not be initialized properly. To make sure if any PCMCIA software has
been loaded in your system and to know more about PCMCIA, please see the next section, “PCMCIA
Software Information”.
EXPCDM.EXE is the device driver for the PCMCIA Sound Card. The parameters are described as below:
/P
is used to set the I/O ports. If you select to use the CD-ROM only, the valid ports are 320-32F,340-
34F, and 360-36F, the default setting will be
/P:320
. When you choose to use the CD-ROM with
Sound, the valid ports are 220-23F, and 240-25F. The default setting will be
/P:220
.
/I
if you want to use the CD-ROM with Sound, it is necessary to set the IRQ number. The valid IRQs
are 5, 7, 9, 10, and the default setting is
/I:10.
/S
is used to enable the Sound feature.
/D
the /D switch indicates the drive name. It can be any name up to 8 characters in length.
4.
Add the following line near the TOP of your AUTOEXEC.BAT:
drive:\path
\
MSCDEX.EXE /D:MSCD001 /M:4
where drive:\path
specifies the DOS directory or the directory containing the file MSCDEX.EXE.
If your AUTOEXEC.BAT file loads a menu program such as DOSSHELL or Windows, you will have to
add the above line to start your menu program. Otherwise, MSCDEX won’t have a chance to load before
your menu program begins.
The example above shows the default setting. The
/D:
switch indicates the drive name. It MUST be
the same name that you specify for the
/D:
switch of EXPCDM.EXE in your CONFIG.SYS file. The
/M:
switch indicates how much memory to allocate for caching information on the CD-ROM. The default
/M:4
caches 8KB.
For more information about the switches of MSCDEX, please type “help MSCDEX” at the DOS prompt.
