Your computer includes 8KB of cache memory. Data that is reused frequently 
during a program is stored in cache memory. Because cache memory is very 
high-speed memory, correct use of cache memory can dramatically decrease 
processing time.

A cache conflict occurs when any system component, either hardware or 
software, attempts to use memory for some other purpose. Cache conflicts are 
rare. If a cache conflict occurs, the cache utility, CACHE482, enables you to 
diagnose and resolve the conflict:

1. Run the cache utility, making a note of the current cache state (the shaded 
area).

2. Select the NONE option and press F2 to reset the computer.

If the problem is resolved by selecting the NONE option, identify the 
component causing the conflict and the memory address involved. The 
documentation for your system components should identify the memory addresses 
they use. Run the cache utility again and select the original cache status and 
deselect the memory range that includes the address that is in conflict. When 
you are finished, press F2 to reset the computer.

RUNNING THE CACHE UTILITY

To run the cache utility:

1. At the MS-DOS prompt (A> or C>), type:

    cache482

    and press <ENTER>.

   The program displays a list of memory address selections. If you toggle an 
   option that is already highlighted, it will be designated non-cache. If you 
   toggle an option that is not highlighted, it will be designated as cached.

2. Use the up and down direction keys to highlight the selection you want. 
   Press <ENTER> to activate the selection.

3. Press F2 to save the selections and reset the computer. Press ESC to cancel 
   the utility.
