Your Macintosh is still set to 24-bit memory addressing and cannot access more
than 8 megabytes. You must set your Macintosh to 32-bit addressing. To do
so, follow these steps:
1) Select Control Panels from the Apple Menu, then select the Memory Control
Panel.
2) Click on 32-bit addressing in the Memory Control Panel.
3) Restart your Macintosh.
Your Macintosh will now be able to access more than 8 megabytes of memory.
