3.12 Upgrading Cache Memory
The S1472 has 256Kb of on-board pipelined burst SRAM and
can be upgraded to 512Kb by adding a Tyan approved 256Kb
cache module. Please refer to your vendor for the approved
upgrade modules.
wRefer to page 9 for the cache jumper settings.
wWhen upgrading to 512Kb cache, you must use a 256Kb "COAST"
module and open jumper J8 and put jumper J7 on pins 1-2
wOnly use Tyan approved 256Kb "COAST" modules when upgrading.
wThe "COAST Module" will only fit in the "Coast Socket" one way and
should install easily.
wwYou cannot disable the onboard cache and install a 512Kb "COAST"
module to get 512Kb of cache. The onboard cache is always used.
