User manual PLEXTOR 12X-3

[. . . ] ---- CHAPTER 10 ---- Using CD-ROM Discs, Caddies, and Trays YOUR TASK: YOUR OBJECTIVE: YOUR METHOD: Learn how to handle, load, and care for your discs. Insert and eject discs properly so your drive operates without interruption. Practice loading discs into caddies and trays. Until the release of the 12PleX, Plextor only manufactured drives with caddy loading mechanisms. Many applications and users continue to require the performance, protection, and/or mechanics of a caddy. [. . . ] See page 34 to ensure you have properly installed this audio cable. If you have a soundboard and CD-ROM drive, but lack an audio cable, contact one of the companies listed on page 65, or Plextor's Technical Support Department, for information on where a cable can be purchased. Device Drivers Need to Be Updated If you can hear an audio CD in your CD-ROM drive when it is in Audio CD play mode (see Chapter 11), but you cannot hear an audio CD with another music CD utility (e. g. , Animotion's MCS CDMaster, CorelCD), your device drivers may need to be updated. If this driver cannot be loaded properly, an error message will normally be displayed on the screen. Watch as the CONFIG. SYS file executes, and look for an error message to appear. You can press the Control and S keys simultaneously to freeze the display in order to read the error message (use the Control and S combination again to continue). If the SCSI device driver cannot be loaded properly, either a software or hardware conflict exists. Software conflicts are generally caused by memory managers; hardware conflicts by two peripherals vying for the same DOS address space. Please read the next two paragraphs on software and hardware conflicts. Software Conflict with Other Device Drivers The SCSI interface board normally designates the CD-ROM driver as the first device driver loaded by the computer. When the computer has a memory manager (e. g. , HIMEM. SYS, 386MAX. SYS, or QEMM. SYS), in most cases the memory manager is loaded first and the CD-ROM driver loaded directly thereafter. 52 12PLEX OPERATION MANUAL CHAPTER 12 ---- Troubleshooting If other device drivers are loading before the CD-ROM driver, place them after the CD-ROM driver. If the memory manager tries to load the CD-ROM driver into high memory (e. g. , DEVICEHIGH or LOADHIGH), disable the function so that the driver is loaded into conventional memory. Hardware Conflict Between the Interface Board and Your Computer The SCSI interface board may be in conflict with another peripheral in your computer. Normally, this conflict can be settled by selecting a different address for the SCSI interface board. In some cases, you may wish to select a different address for the conflicting peripheral. If the driver still does not recognize the interface board, follow these steps: 1) Remove all non-essential peripherals from your computer (e. g. , network boards, fax boards, etc. ) and their device drivers from the CONFIG. SYS and AUTOEXEC. BAT files. 2) Reboot the computer and ensure that the CD-ROM device driver recognizes the SCSI interface board. 3) Turn off the computer and reinstall each peripheral and its device drivers one at a time. 4) Repeat steps 2 and 3 until the problem reoccurs. This means that the problem is with the last peripheral you installed. Improper MSCDEX Installation The Microsoft CD-ROM Extensions (filename: MSCDEX. EXE) or equivalent files from Corel (CORELCDX. EXE) are required to run your CD-ROM drive under MS-DOS or DR DOS. If the SCSI driver was successfully loaded, check for proper installation of MSCDEX. EXE by rebooting the computer and watching the AUTOEXEC. BAT file as it executes for an error message. [. . . ] Hardware Conflict If the SCSI interface board uses DMA channels, try changing the selected DMA channel. See the instruction manual for your SCSI interface board. Memory Manager Conflict If the SCSI interface board uses memory-mapped addressing or has a BIOS, exclude the addresses from the memory manager. See the instruction manual for your SCSI interface board. [. . . ]
