Making a RAM disk the startup disk
If you have 6 MB or more of memory, you can make a RAM disk
your startup disk.
1. Create a RAM disk.
2. Locate and open the Installer program on the Install
disk.
3. Install a minimal System Folder on the RAM disk.
See the instructions on installing customized system software
in this chapter.
4. Choose Control Panels from the Apple (K) menu.
5. Open the Startup Disk control panel.
6. Select the RAM disk as your startup disk.
7. Choose Restart from the Special menu.
The RAM disk is now your startup disk. Be sure to keep a System
Folder on your hard disk as well, in case the contents of the RAM
disk are erased. Also, keep a copy of the RAM disk contents on
another disk. (Don’t keep two System Folders on a single disk.)

Important: If your computer has a built-in floppy disk drive,
the contents of the RAM disk are erased when you choose
Shut Down, though the RAM disk itself is not removed.
