Installation Overview
Cache Memory
The G586VPM provides a cache module slot rather than a
build-in cache. The system board can be configured to
three different cache sizes: 256KB (default), 512KB and
1MB. Insert the cache module into the cache module slot.
The system board is equipped with a 8Kx8 Tag RAM
mounted on location U6. Install a second Tag RAM on
location U7 if you are using 512KB cache with 32-byte
line size or 1MB cache with 64-byte line size. We recom-
mend that you use an IDT brand of cache module.
