The extentions in this archive will enable Toast to recognise Archos' 'Slim CDRW' on a Mac.
Drop onto StuffIt Expander, mount the image and follow the instructions!
Only tested with Mac OS 9.x
Alternatively, you can go to www.roxio.com and dowload the updater yourself... but you need Toast 5 to do this.
The extentions in the archive will work for any version of Toast.
