Apple Power Macintosh (7100 Series) - Manual (Page 79)

You can’t start an application program or it quits unexpectedly. Or, when you try to open
a program, you see a message that not enough memory is available.
One of the following is probably the cause:
m The Macintosh ran out of memory.
Quit the programs that you have open and then open the program you want
to use, or restart your Macintosh.
Use the Memory control panel to turn on virtual memory. (This is
especially important if you have a Power Macintosh computer or Power
Macintosh upgrade card and are using programs designed specifically for
the Power Macintosh.) For more information on virtual memory, see the
“Memory” topic of Macintosh Guide, available in the Guide (h) menu.
m The program needs more memory.
Use the program’s Info window to give it more memory. For more
information on increasing a program’s memory, see the “Memory” topic of
Macintosh Guide, available in the Guide (h) menu.
m The program requires special hardware, such as a floating-point unit
(FPU), and your computer doesn’t have the hardware installed.
Check the documentation that came with the program to find out if the
program requires a Macintosh with special hardware, such as an FPU. Then
check the Technical Information booklet that came with your Macintosh to
find out if your computer is equipped with such special hardware, or if the
hardware can be installed. Consult your Apple-authorized service provider
for information on installing special hardware in your computer.
