System Memory
The system comes with between 16 MB and 256 MB of SDRAM installed in dual in-line
memory module DIMM sockets on the system board.
The memory configuration consists of two sockets. The DIMM memory sockets accept
168-pin, 64-bit (non-parity) 8-, 16-, 32-, 64-, and 128-MB DIMMs. Table 1-5 lists the
supported DIMMs.
