General questions
After I install System 7.5, my computer will not start up properly. Can I start up from a
floppy disk?
Yes. A startup floppy disk is included with the software. In addition, the
Macintosh System 7.5 Group Upgrade CD contains a 1.4 MB disk image of the
System 7.5 Disk Tools disk. This disk contains a minimum system software
configuration and should be used only to start up the system for
troubleshooting when other methods fail.
Note: This startup floppy disk will not work on Macintosh and PowerBook
computers introduced after August 1994. If you have one of these models, use
the Disk Tools disk that came with your computer as a startup floppy disk.
I’ve installed a system extension (INIT) that isn’t compatible with System 7.5, and my
computer won’t start up. How can I get the system to bypass it?
Restart your computer and hold down the Shift key until you see the Welcome
to Macintosh message. System extensions will not be loaded. When the
computer is running, drag this extension out of the System Folder.
You can also use the new Extensions Manager control panel to turn off the
extension. (See Chapter 6 of the Macintosh System 7.5 Upgrade Guide for more
information about this control panel.)
