Some hard disks that have been formatted with older versions of HD SC Setup
may require an updated driver in order to function with Virtual Memory. IT
IS NOT NECESSARY TO REFORMAT THE DRIVE. If the Memory control panel
indicates the drive needs updating, follow the instructions in the System 7
Personal Upgrade Kit to use HD SC Setup to update the driver.
All Apple internal and external hard disks are compatible with all
Macintosh systems that have a SCSI interface.
The version of Apple HD SC Setup that ships with all hard disks is
compatible with System 7, but version 2.0.4 is the recommended version.
The upgrade to version 2.0.4 is free, and the files can be found in the
Upgrade folder on the System 7 Information bulletin board, as well as on
the System 7 Group Upgrade Kit CD.
