Startup Disk options in Mac OS 9.2.2, with support for switching to Mac OS X.īefore Mac OS X arrived, there were few cases of installing more than one System Folder on a single un- partitioned hard drive. Multiple drives became more commonplace in large tower configurations, such as the Macintosh Quadra 900. Starting in System 7, released in May 1991, 'Startup Device' was renamed to 'Startup Disk', which became a separately-launchable control panel of its own. The Macintosh II also had sufficient space to daisy chain more than one internal SCSI drive.

Earlier versions of the system software would automatically default to the floppy drive instead of the hard drive if a bootable floppy disk was inserted, but the Macintosh SE and II were both available in dual floppy versions. The control panel first appeared as ' Startup Device' in October 1987, which could be accessed through the Control Panel desk accessory of System 4.2 to support the Macintosh SE and II, which were the first Macs to contain more than one internal drive. On a Macintosh Centris 610 or newer Mac, an alternate method to boot from the CD-ROM drive was to simply hold down the 'C' button while starting up. This method was sometimes used to boot from a system installer disk (such as a CD-ROM) instead of the default internal drive. A different startup disk can be selected by clicking a another icon. The first (or selected) icon in this control panel represents the volume containing a System Folder that will be loaded upon the next reboot. For users of classic Mac OS, this control panel was useful for Macs containing, or attached to, more than one bootable drive, such as a CD-ROM, floppy drive, or hard drive.
