In the past, the Apple CD-ROM extension has not offered support for the vast majority of CD-ROM drives. Most non-Apple CD-ROM drives, including drives used in Power Computing computers,were not supported by the Apple CD-ROM extension and so could not be mounted by that extension.
Apple CD-ROM 5.3.1, which ships as part of MacOS 7.6, offers generic support for 6x or faster SCSI CD-ROM drives. This enables non-Apple CD-ROMs to mount CDs without the presence of an additional third-party driver such as the FWB CD-ROM Toolkit used by Power Computing.
When a customer upgrades an existing System Folder to MacOS 7.6, the CD-ROM Toolkit is not removed (as it is a third-party extension). As the Apple CD-ROM extension loads before CD-ROM Toolkit, it provides support for the CD-ROM. This causes CD-ROM Toolkit to alert the user to the fact that the drive is supported by another driver.
Though the Apple CD-ROM extension will provide limited functionality, Power Computing recommends that Power customers use CD-ROM Toolkit as their preferred CD-ROM driver as it is more robust and offers higher performance.
In order to eliminate the CDT error message, add a space before the CD-ROM Toolkit extension's name. This will cause CDT to load before Apple CD-ROM, preventing the error message.
