HARDWARE SETUP
4.2.2 L2 CACHE MEMORY INSTALLATION
The PT-5IVL system board will support one bank direct-mapped second level cache, and provides either 256KB
or 512KB cache memory, using synchronous pipeline-burst SRAMs. (
Note that this system board does not
support asynchronous or burst SRAMs for the L2 cache memory ) Both Write Back and Write Through cache
update policy are supported.
The second level cache is supported via a COAST (Cache-On-A-STick) module, there is no jumper needed for
end-user while using L2 cache memory, just insert the COAST module into the SRAM module slot (CN10),
then the cache memory size will be detected by system BIOS automatically.
Note : The COAST modules design must comply with Intel COAST (Cache-On-A-STick)
module specification revision 2.0 or later.
