[. . . ] ---- CHAPTER 11 ---- Using CD-ROM Discs and Caddies YOUR TASK: YOUR OBJECTIVE: YOUR METHOD: Learn how to use a caddy and how to handle and care for your discs. Insert and eject caddies properly so your drive operates without interuption. Practice loading discs into caddies, and caddies into drives. Plextor's CD-ROM drives use an industry-standard disc caddy to protect the disc from scratches and contamination. A standard caddy is made of plastic and has a metal shutter on its bottom which slides open and shut. [. . . ] If it works, you should have the defective disc replaced. Symptoms · · · · Invalid Drive Specification No Device Found No SCSI Interface Board Found or No Response from SCSI Interface Board · No Drives in Use Additional Symptom Error Appears upon Initial Installation of the CD-ROM Drive and Device Driver Software Possible Causes and Solutions Improper SCSI Device Driver Installation Your computer needs a SCSI software device driver to link the SCSI interface board to the CD-ROM drive. 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. , 52 PX-43CH/PX-45CH OPERATION MANUAL CHAPTER 13 ---- Troubleshooting HIMEM. SYS, 386MAX. SYS or QEMM. SYS), in most cases the memory manager is loaded first and the CD-ROM driver loaded directly thereafter. 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. Improper MSCDEX Installation The Microsoft CD-ROM Extensions (filename: MSCDEX. 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. SCSI Interface Board Not Properly Seated If the SCSI interface board is not fully seated into the computer's expansion slot, the device driver software will not recognize it. Inspect the interface board where it seats into the connector on your computer's motherboard. [. . . ] Bad Connection Between the CD-ROM Drive and the SCSI Interface Board Inspect the cable, drive, and interface card for recessed, broken or bent pins. If a ribbon cable is used, inspect for any signs of distress, such as kinking. Ensure the red stripe side of the ribbon cable plugs into pin 1 on both the drive and the interface board. Audio CD Disc In the Drive Plextor CD-ROM drives are capable of playing high-quality audio when used with appropriate audio playback software or when the drive is set to Music CD Player Mode (see Chapter 12).
