To install the CD-ROM device driver, the syntax in CONFIG.SYS
is as follows:

DEVICE=VIDE-CDD.SYS /D:MSCD001 [/P:xxx,yy] [/L:xx]

where [/P:xxx,yy]
specifies the IDE port which is connected to the drive and the
interrupt request.

'xxx' is the base address (hexadecimal notation) of IDE port.
xxx = 1f0 : Port 1
170 : Port 2
1e8 : Port 3
168 : Port 4

'yy' is the interrupt number (decimal notation) of the
corresponding IDE port.

[/L:xx]
specifies the message language. Available options are listed
as below:

xx = US : English (the default language)
GR : German
FR : French
SP : Spanish
IT : Italian
JP : Japanese

For example, when eight drives are installed, the command
line in the CONFIG.SYS file could be entered as follows:

DEVICE=VIDE-CDD.SYS /D:MSCD001 /P:1f0,14 /P:170,15 /P:1e8,12 /P:168,10

NOTE:

Our device driver will automatically search the drives for 4 ports
up to 8 drives, and the ports are 0x1f0, 0x170, 0x1e8 and 0x168 with
interrupt number 14, 15, 12 and 10 as default, respectively. If your
IDE ports and their respective interrupt numbers are the same as
those mentioned above, you don't have to specify them verbosely.

---------------------------------------------------------------------------

To enable the CD-ROM drive to read CD-ROM discs using the High
Sierra or ISO 9660 format, you not only need to install the CD-ROM
device driver, but also need to insert the following line into your
AUTOEXEC.BAT file:

MSCDEX /D:MSCD001

To have a detail knowledge about the MSCDEX.EXE program, please
refer to MS-DOS user manual.

Starting the Drive

1. Press the Eject button. The tray is ejected from the drive.
2. Place the disc in the tray with the disc label side facing up.
3. Press the Eject button or press the tray panel lightly to close
the tray. The drive should be in its normal operating position
now.
4. Press the Audio Play/Skip track control button to play or skip
one track of Audio CD without executing application software.

NOTES: 1. Do not force the tray to open manually.
2. When not using the drive, keep the tray closed to
prevent the dust and dirt contamination.
3. Do not press down hard on the tray when loading a
disc, because it could damage the tray and cause
the drive to malfunction.
4. Do not insert any foreign objects into disc tray.


Optimizing the Drive

Although this CD-ROM drive works fine with the default setting of
any system BIOS, it takes the advantages of some special settings
in modern BIOS. To fully utilize this CD-ROM drive, PIO mode 4 or
DMA mode 2 is recommended for the setting of the system BIOS. If
your system BIOS does not allow you to change the PIO mode, run
the CHPIO.EXE in the installation disk. It will work for most
modern systems.

NOTES: 1. The change made by CHPIO.EXE will not be saved to
BIOS, so you may want to add it in the AUTOEXEC.BAT
file. Or as the system reboots, the BIOS will
automatically reset its PIO mode to the original
settings.
2. Some older systems may not work properly under PIO
mode 4. If such thing happens, reboot your system,
then the BIOS will automatically reset the PIO made
to its original setting.


Examining the Drive

In the installation disk, a program named DTR.EXE can be used to
examine the performance of the CD-ROM drive. To get the proper
performance, the following procedures should be taken:

1. Boot your system from DOS. If you use Windows 95, press F8 while
booting, then select "Command prompt only" or "Previous version
of MS-DOS" of Microsoft Windows 95 Startup Menu.
2. Insert a large capacity (>600MB preferred), single session, pure
data CD-ROM disk with no scratch or dust.
3. Run the DTR-EXE in the installation disk.

This program will test the data transfer rate at various areas of a
CD-ROM disk, and plot a curve of the data transfer rate.

For disks with scratches or dust, the data rechecking and corrections
may cause the data transfer rate to drop temporarily.

Q. Why cannot I do a directory (dir) on a good ISO-9660 format disc
on my CD-ROM drive although it is ready?
A. Your CD-ROM drive might work on PIO mode zero only. When your PC
system is configured in a faster IDE interface mode, this CD-ROM
drive might get this kind of communication problem. The solution
will be that you have to turn down the interface speed between
the CD-ROM drive and your PC system through BIOS or interface
card setting. After the configuration is changed, you need to
reboot the system.

Q. Why is it slow to read files for my CD-ROM. How to get it faster?
A. The MSCDEX.EXE allocates memory for caching information on the
CD-ROM. You can set the /M: to determine how many sector
buffers MSCDEX allocates when it installs itself. Typically, each
drive should have a minimum 4-5 buffers per drive and the higher
this value is, the better the drive performance would be.

Q. I have an enhanced IDE card with two ports, but I cannot install the
CD-ROM drive on the secondary port properly.
A. The secondary port on some enhanced IDE card (eg. CMD0640x) is left
un-opened when the PC system is initially powered on. Under such a
condition, the CD-ROM device driver will not act stably when this
CD-ROM drive installed. To resolve this problem, you can install
the device driver bundled with your enhanced IDE card to open the
secondary port.

Q. The SKIP button doesn't skip while a 'CD PLAYER' like program is
playing.
A. Based upon the design philosophy of this CD-ROM drive, the application
program has a higher priority than the manual pressing buttons so
that the interference between "manual pressing button" and
"application program" can be avoided. Therefore, during play under
application program, the CD-ROM drive will not respond when the
"SKIP" button is pressed. Besides, the tray will be opened when the
"STOP" button is pressed.
