(4)Installing Pipeline Burst SRAM
This mainboard features a 256K or 512K cache memory. It also
features a cache memory extension socket (COAST) in order to permit you
to upgrade 256K cache to 512K, and this with only one JC1 to choose from.
Installation is very easy. Refer to the table below:

<Notes>1. If your mainboard features a 512K cache when it is delivered
from the factory (Mode 6 in the table), the mainboard will not
have any cache extension slot (COAST) or JC1 jumper.
2. The configurations listed in the table are all the possible
configurations reserved when the board was designed. The
actual configuration when the board is delivered depends
mainly on the demands of the market.
