2.5.1 UPGRADING CACHE

The mainboard is available with an optional 256KB, 512KB, or 1MB cache
memory on-board. User can upgrade cache memory by installing additional
SRAM (Static Random Access Memory) chips in sockets U10-U17; U9.
The speed of the SRAM chips needed depends on the clock speed of the
microprocessor:
75,90,100,120,133MHz CPU requires 15ns (tag and data) SRAM chips.

2.5.2 CACHE SIZE AND MEMORY LOCATIONS

The table on following page describes the chip capacity and socket location
required for each cache size configuration. User can use 32Kx8-bit,
64Kx8-bit, or 128Kx8-bit SRAM chips in the Data RAM sockets, and
8Kx8-bit, 16Kx8-bit or 32Kx8-bit SRAM chips in the Tag RAM socket.
