Apple 6400 appendix Sad Macintosh icon appears and the computer won’t start up

If repairing the disk doesn’t help, follow the instructions in Chapter 7, “Reinstalling Your Computer’s Software,” to reinstall system software on your startup hard disk.

A disk icon with an X appears in the middle of the screen and a floppy disk is ejected from the disk drive.

This icon indicates that the floppy disk you tried to start up from is not a startup disk. (When you turn on your computer, it looks first in the floppy disk drive for a disk containing system software. If the disk in the drive does not contain system software, the computer ejects the disk and looks on its internal hard disk for system software.)

Wait a few seconds. The computer should start up from its internal hard disk. Make sure you insert floppy disks only after the computer has begun starting up.

A “sad Macintosh” icon appears and the computer won’t start up.

This icon indicates that your Macintosh cannot start up because of a problem with the system software or the computer hardware.

Eject any floppy disks by turning off the computer and then holding down the mouse button while you turn the computer on again. Try starting up with the Macintosh Performa CD: Performa Software. Do this by inserting the CD-ROM disc into the CD-ROM drive and holding down the C key while you restart the computer. (See the section “Starting Up From the Macintosh Performa CD: Performa Software” later in this chapter if you need more help.) If the “sad Macintosh” icon appears again, consult the service and support information that came with your computer for information on contacting an Apple- authorized service provider or Apple for assistance.
