Support for ATAPI CD-ROM drives (such as in the PowerBook 1400) was first introduced in version 5.2 of the Apple CD-ROM driver.
The current version of the Apple CD-ROM driver supports both Apple and industry standard ATAPI CD-ROM drives. Qualified ATAPI version 2.6 compliant drives should have full multimedia support. UDF support has been included in all drivers.
There are CD-ROM drives that do not support all of the ATAPI specification, and therefore cannot be accessed by the Apple CD-ROM driver.
Apple has not tested or qualified any third party drives. Nonetheless, if the drive manufacturer conforms fully to the ATAPI 2.6 standard, it should work.
