Level 2 Cache Options

The Level 2 cache on the PR5 greatly speeds up system

operation. There will be at least 256KB of very fast Pipe-

line Burst Static RAM (SRAM) cache memory mounted

either on the mainboard or on a cache module that in-

stalls in the cache socket. You can upgrade the Level 2

cache to a maximum of 512KB regardless of whether the

memory is on the board or on a module.

If there is 256KB of cache memory mounted on the

mainboard, you can use a 256KB cache module to up-

grade the Level 2 cache to 512KB. See the cache options

in the following table. Jumper JP1 sets the cache size.
