INSTALLATION .III (Jumpers)

III.INSTALLATION3.Total Level 2 Cache Size Setting (JP5)

This jumper sets the total amount of L2 cache that is present. If you have both onboard cache chips (see "Map of Motherboard" for locations) and a Cache Expansion Slot, then you have 256KB. If you only have onboard cache chips, then you have 512KB. An "ASUS" or "COAST" 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 page 14 "SRAM 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.
