3. Total Level 2 Cache Size Setting (JP4)
This jumper sets the total amount of L2 cache that is present. If you have two
cache chips onboard (see "Map of Motherboard" for locations), then you have
256KB. A cache module can be used to upgrade the 256KB version to 512KB.
If there is no onboard cache, you may install a cache module of either 256KB or
512KB. IMPORTANT: See "External Cache" for installation procedures.
Regardless of your cache combination, set the following jumpers according to
the total amount of L2 cache that is present onboard and installed as a module.
