Apple 120 Series user manual Sad Macintosh icon appears, and the computer won’t start 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 Disk Tools floppy disk or (if you have a built-in CD-ROM drive) with the CD-ROM disc that contains system software. (For instructions on how to start up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this chapter.) 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.

The hard disk icon does not appear on the desktop.

If you don’t see a hard disk icon on the desktop, try the following:

mUse the Drive Setup program to make the disk available. Drive Setup is located in the Apple Extras folder. For instructions, start Drive Setup, then choose Drive Setup Guide from the Guide (h) menu.

mIf the hard disk is internal, shut down your computer, wait at least 10 seconds, and then turn it on again.

mIf the hard disk is external, make sure that it is turned on and that its cable is connected firmly; then restart the Macintosh.

mCheck the ID numbers of all SCSI equipment connected to your computer. No two SCSI devices on the same SCSI chain can have the same ID number. In addition, there are special requirements for assigning SCSI ID numbers that don’t conflict with your computer or its internal storage devices. See Chapter 3 and the manuals that came with your SCSI equipment for information on setting SCSI ID numbers.
