Apple IIe Card - Manual (Page 133)

To lock the IIe Prefs file, follow these steps:
Before you begin: Make sure you’re in the Macintosh environment.
1. Select the IIe Prefs file by clicking its icon once.
2. Choose Get Info from the File menu.
3. Click the Locked checkbox until an X appears in it.
4. Close the Info window.
Click the close box.
Purchasing and installing an optional jumper cable
To protect the Option Panel settings more permanently, you can
purchase an optional jumper to use with the Apple IIe Card. Once your
dealer installs the jumper on the Macintosh LC logic board, users will still
have access to the Apple IIe Option Panel buttons, but they will not have
access to any of the panels used to change Option Panel settings. See
your authorized Apple dealer for more information.
Hiding the preferences file
To prevent someone from accidentally throwing away the IIe Prefs file,
you can move the file to the System Folder on your startup disk or to
the Preferences folder inside your System Folder.
If you’re a floppy disk startup person, drag the IIe Prefs file into the
System Folder on the
IIe Startup Disk; if you’re a hard disk startup
person, drag the file into the System Folder on your hard disk.
