SIMM lnstallation
Your computer comes with 8MB of memory on two 4MB
SIMMs. You
1MB, 2MB, 4MB, 8MB, 16MB, and 32MB SIMMs (when
readily available).
The SIMM sockets are organized in two banks (Bank 0 and
Bank 1) consisting of two sockets each. You must install the
same type of SIMM in a bank.
The SIMMs you install must be 32-bit or 36-bit, 72-pin, 70ns,
tin-plated, fast-page mode, parity/no parity DRAM. The
table below lists the 16MB and 32MB SIMMs that are
approved for use in your system. You can install these
SIMMs or their equivalents.
