======================================================================= A B O U T C D - R O M D E V I C E D R I V E R ======================================================================= Instructions for manual loading of the driver ======================================================================= 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. ======================================================================= O p e r a t i n g t h e D r i v e ======================================================================= 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. ======================================================================= F r e q u e n t l y A s k e d Q u e s t i o n ======================================================================= 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.
