- 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.

-
- 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:<value> 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.
