Switch S2 is used to select the size of each SIMM. If the SIMMs are
4M×32 or larger, S2 should be in the OFF setting as shown in
Figure 4-6a. For SIMMs smaller than 4 M × 32, use the ON setting as
shown in Figure4-6b.
Figure 4-6. SIMM Size Configuration
Refer to Table4-1 for how to adjust the switch (ON or OFF) for all
supported DRAM configurations. Many of the DRAM options are
