Secondary Cache Installation

The system board comes standard with 8 KB of cache integrated into the Intel486SX-33
and the Intel486DX2-66 CPUs. The Intel486DX4-100 has 16 KB of integrated cache. The
CPU cache is called the primary cache and any cache not integrated into the CPU is call
secondary cache. The optional secondary cache kit consists of a 256-KB SIMM. The sec-
ondary cache is installed into the socket on the system board shown in Error! Reference
