Problems With Connecting A CR521, 523, 531, 563 CD-ROM Drive To A Sound Blaster Card

• Check that your Sound Blaster card has a Panasonic CD-ROM interface.
• Note the drive-access light on the CD-ROM drive. If the light does not come on when the machine is powered up, check the power connection going to the CD-ROM drive.
• Make sure the I/O address listed in the CONFIG.SYS reflects the hardware settings of the sound card that the CD-ROM drive connected to.
• If the drive is connected to a CT1810 CD ROM interface card, make sure a /T:2 switch exists on the SBCD.SYS line in the CONFIG.SYS. Remember that this switch must not be present if the CD-ROM drive is connected to the Sound Blaster.
• Backup your original AUTOEXEC.BAT and CONFIG.SYS files. Create a custom AUTOEXEC.BAT and CONFIG.SYS containing only the Sound Blaster and CD-ROM information.
• Check the connections of the CD-ROM ribbon cable to ensure they are securely connected.
• Remove all non-essential cards from the system. If necessary, change the base I/O address of the Sound Blaster.
• If the above items have been checked, then try with another CD-ROM ribbon cable, and not a hard drive cable.
• If the CD-ROM drive does not work after replacing the cable, the CD-ROM or the interface card may be defective.
