Apple Power Macintosh 5260 Series - Manual (Page 52)

Special memory requirements
Some Power Macintosh programs may be slightly larger than other programs
and may take up more memory. If you find that you are running out of
memory when you use your Power Macintosh programs, you can use space
on your computer’s hard disk as additional memory. For instructions on how
to use hard disk space as memory, see the “Memory” topic area of Macintosh
Guide, available in the Guide (h) menu.
You can also add more memory to your computer, as described in “Installing
Memory (DRAM SIMMs)” in Appendix B.
Shared libraries
Power Macintosh programs use special files called shared libraries. These files
help the programs to run more efficiently, and can be used by more than one
Power Macintosh program simultaneously. Any necessary shared libraries are
installed automatically in the System Folder when you install Power
Macintosh programs.
If one of these programs requires a shared library and there is not enough
memory available for the shared library, you’ll see a message that the program
could not be opened because of insufficient system memory. If this happens,
see the “Memory” topic area of Macintosh Guide, available in the Guide (h)
menu, for instructions on turning on virtual memory.
If a required shared library is missing, you’ll see a message that the program
could not be opened because the shared library could not be found. If this
happens, follow the directions that came with your program to reinstall the
program. If the shared library is still missing, contact the program’s
manufacturer for assistance.
Using older Macintosh programs
If you experience problems using an older Macintosh program, it may be
incompatible with your Power Macintosh. You may be able to use your older
program if you change the Modern Memory Manager setting in your
Memory control panel. For detailed instructions on using older programs
with your Macintosh, see the “Working with Programs” topic area of
Macintosh Guide, available in the Guide (h) menu.
