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. The 512KB version cannot be upgraded any further. If there is no onboard cache, you may install a SIMM cache module of either 256KB or 512KB. IMPORTANT: You must set "Total Level 2 Cache Size Setting" jumper on page 8 when changes are made to your cache size. 42 Pins III.
