Setting the Extended Memory Caching

Extended memory caching allows your system to work much faster. When you cache portions of memory, the computer copies information from that memory into a high-speed cache buffer. Your system can find information more quickly in the cache buffer than when it looks for it in the system memory. This greatly improves the speed at which your system performs.

Note

Caching is active only when your computer is operating at 25 MHz (high) speed.

The Equity 386/25 PLUS automatically enables memory caching for the 640KB of base memory in your system. For the memory above 1MB, the Setup program allows you to turn extended memory caching on or off. The default setting is ON for all the extended memory currently installed in your system from 1MB up to the maximum.

Most of the time, you should cache all of your extended memory to maximize the performance of your 32-bit computer. However, if you install an optional memory card that “shares” memory with any of your other system memory, you should turn caching off in memory areas that are shared. See the manual that came with your memory card to see if this is necessary.

To check or change the extended memory cache setting, follow these steps:

1.At the main Setup menu, highlight Cache memory. You see the following cache memory table:
