Figure 3. SIMMs and Corresponding DRB Registers
The following 2 examples describe how the DRB Registers are programmed for cases of single-sided and
double-sided SIMMs on a motherboard having a total of four 8-byte or eight 4-byte SIMM sockets.
Example #1
The memory array is populated with four single-sided 1 MB x 32 SIMMs, a total of 16 MBytes of DRAM. Two
SIMMs are required for each populated row making each populated row 8 Mbytes in size.
DRB0=02h
DRB1=04h
DRB2=04h
DRB3=04h
DRB4=04h
DRB5=04h
populated (2 SIMMs, 8 Mbytes this row)
populated (2 SIMMs, 8 Mbytes this row)

Example #2
As an another example, the memory array is populated with two 2 Mbytes x 32 double-sided SIMMs (one
row), and four 4 Mbytes x 32 single-sided SIMMs (two rows), yielding a total of 96 Mbytes of DRAM. The
DRB Registers are programmed as follows:
DRB0=04h
DRB1=08h
DRB2=10h
DRB3=18h
DRB4=18h
DRB5=18h
populated with 16 Mbytes, 1/2 of double-sided SIMMs
the other 16 Mbytes of the double-sided SIMMs
populated with 32 Mbytes, one of the sided SIMMs
the other 32 Mbytes of single-sided SIMMs
