Apple 9600 manual 139

mUse the Memory control panel to reduce the size of the disk cache, remove or reduce the size of your RAM disk, or turn on virtual memory. For more information, see Macintosh Guide (or Mac OS Guide), available in the Guide (h) menu.

Note: If you are using a Power Macintosh MP model, you may not

want to turn on virtual memory. For more information, see “Using Power Macintosh MP-Compatible Application Programs” in Chapter 3, “Installing and Using Software.”

Note: If you have both virtual memory and a RAM disk turned on in the Memory control panel, don’t set both of them at or near their maximum values. Doing so can result in unpredictable or reduced performance by your computer. (RAM disk uses random-access memory, or RAM, as if it were a hard disk.)

mDisable system extensions that you don’t need. For more information, see the topic on system extensions in Macintosh Guide (or Mac OS Guide), available in the Guide (h) menu.

mIf you have installed system software additions from the Apple Extras folder such as Apple VideoPhone or PlainTalk, you may want to remove them if you are not using them. (This software can decrease the amount of memory available for use by application programs.) To remove a system software addition, locate and run the Installer for the software, and use its “Custom Remove” option to remove it.

mIf you frequently want to open more programs than memory allows, you may want to install more random-access memory (RAM). See Chapter 8, “Installing PCI Expansion Cards and Additional Memory.”
