TITLE Apple IIGS: How to Mix a 3.5-inch Drive with Other Drives Article ID: 7525 Created: 7/1/91 Modified: 8/9/91 -------------------------------------------------------------------------------- TOPIC I am using an Apple IIGS with a DuoDisk drive and a single 5.25-inch drive. The controller cards are in slots 5 and 6. I want to use a 3.5-inch drive along with the other drives. I installed an Apple UniDisk 3.5-inch drive with its controller in slot 4 and tried slot 7 with no success. I changed the slot settings under the Control Panel each time. How can a 3.5-inch drive be used with the described 5.25-inch drives? -------------------------------------------------------------------------------- DISCUSSION Try this configuration: 1) Plug the UniDisk 3.5-inch directly into the back of the computer (no controller). 2) Plug the DuoDisk into the port on the UniDisk 3.5 disk (no controller). 3) Plug the single 5.25-inch UniDisk into a controller card in slot 7. Set the Control Panel as follows: slot 5 smart port slot 6 disk port slot 7 your card startup scan This configuration tries first to start up from the UniDisk 5.25. If no disk is found, then it looks to drive 1 of the DuoDisk. If no disk is found, then it goes to the UniDisk 3.5.
