Before the release of 7.6, 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.
However, with the release of MacOS 7.6.1, Apple shipped the older driver which does not support the CD-ROM drives that ship with Power Computing's machines. In order for Power Computing customers to be able to use their CD-ROM drive FWB's CD-ROM toolkit must be installed. An alternative is to do a clean install of 7.6 and use the driver that comes with it.
