III. INSTALLATION Static RAM (SRAM) for Level 2 (External) Cache The motherboard you purchase may have either 0KB, 256KB, or 512KB onboard. 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: You must set "Total Level 2 Cache Size Setting" jumper when changes are made to your cache size. 38 Pins 42 Pins III.
