System Overview

Main Memory
The two DIMM sockets on the system board can accommodate combinations of
16-, 32-, 64-, and 128-MB DIMMs up to a total memory capacity of 256 MB.
Although 64-bit nonparity EDO DIMMs are recommended, 72-bit parity
DIMMs can also be installed. The standard main memory is 16 MB of high-
speed (60-ns) nonparity memory. For optimum performance, install DIMMs in
consecutive sockets starting with socket DIMM_A.
System Board Jumpers
Figure 1-12 shows the location of the jumper blocks on the system board. See
Table 1-2 for the jumper descriptions and settings.
