When you start up the computer, you see a message about the system software.
mThe system software on the startup disk you’re using may be incomplete or damaged or may be the wrong version. Make sure you’re using the correct disk as a startup disk.
mIf you’re sure you’re using the correct startup disk, you may need to reinstall system software. See “Installing System Software” in Chapter 11.
When you start up, a disk icon with a blinking question mark appears in the middle of the screen and stays there for longer than 15 seconds.
This icon indicates that your Macintosh cannot find the system software it needs to start up. One of the following is probably the cause:
mYour computer may be having a problem recognizing external SCSI (Small Computer System Interface) equipment, such as hard disks and scanners that you may have connected.
Shut down your computer, turn off all external SCSI equipment, and disconnect the first SCSI device in the chain from your computer’s SCSI port (marked with the g icon). Then restart the computer. If the computer starts up after you disconnect your SCSI equipment, refer both to the manuals that came with the equipment and Chapter 7, “Connecting Additional Equipment,” which has information on the proper way to connect SCSI equipment and assign SCSI ID numbers.
If you have a printer connected to your computer’s SCSI port, make sure your printer is connected properly. Most printers connect to the printer port, not the SCSI port. Check the manuals that came with your printer for information on how to connect it properly.
