Problems using the Turbo 601
This section helps with problems you might encounter using the com puter
after installing the Turbo 601.
You can't start up the com puter
When you turn on your computer, you see a “ bom b” message.
• You probably have an incompatible item in the System Folder. To turn off
potentially incompatible items in the System Folder, hold down the Space bar
while you restart your computer. When the Extensions Manager opens,
choose “ System 7.X Only” from the Sets pop-up menu. Close the Extensions
Manager to resume startup. All extensions are turned off, except those
installed with System 7.5 or greater. Once you have started up the computer,
you need to determine which startup program is causing the problem. For

Disk Tools disk that came with the upgrade card. When you have restarted
the computer, follow the instructions in “ Performing a Clean Installation” in
