Section 3: Installing the M54E2

Installing Cache Memory

In addition to the 16K of internal (L1) cache built into the Pentium proces- sors, the M54E2 also supports external (L2) cache. The M54E2 is available with 256K or 512K external cache.

To upgrade to 512K cache, install eight 32Kx8-15ns 3.3V SRAMs into the open SRAM sockets (Figure 3-2). After installing the cache upgrade, refer to Table 2-4 for the correct external cache jumper settings.
