Mac OS 8.5: Iomega 6.0.1 Driver and Virtual Memory

Mac OS 8.5 includes support for the use of removable media (like the Iomega Jaz drive) for Virtual Memory. However, the currently shipping version of the Iomega driver included with this release does not support the use of an Iomega drive for Virtual Memory.
A new driver, Iomega driver version 6.0.2, is under development and will support this new feature. The 6.0.2 driver should be available for free download at 'http://www.iomega.com' in September 1998.

If you wish to install Mac OS 8.5 onto a Zip or Jaz disk, you should change the backing volume used by Virtual Memory to a non-removeable volume. To do this, disable extensions while restarting the first time by holding down the shift key. Open the Memory control panel and turn on Virtual Memory. The Memory control panel will let you set the VM backing volume to a volume that is compatible with VM.
