Only follow the section about installing on WB 2.0 or higher. Remove everything related to WB 1.3 and below.
Basically you only need to copy AmiCDFS to L: and to copy CD0 to Devs:DosDrivers. Then edit CD0 in order to fill in the name of your SCSI driver (aka device) and the SCSI ID (aka unit) of your CD drive.
