3.12 Upgrading Cache Memory

cache module. Please refer to your vendor for the approved
upgrade modules.

Refer to page 9 for the cache jumper settings.

When upgrading to 512Kb cache, you must use a 256Kb "COAST"

Only use Tyan approved 256Kb "COAST" modules when upgrading.

You cannot disable the onboard cache and install a 512Kb "COAST"
module to get 512Kb of cache. The onboard cache is always used.
