The customer needs to upgrade to the IOMEGA RCD (Removable Cartridge Disk) driver version 7.00. The driver can be obtained from IOMEGA only, Tandy does not have an upgrade. IF the DCS is being used as a boot device, it will require a DCS ROM upgrade as well. The driver can be obtained from IOMEGA directly at 1-800-456-5522 or on their bulletin board at 801-778-4400. Any information about the upgrade and how to use it needs to be directed to IOMEGA at the above numbers. (ABO/all-08/31/95)
