A worksheet is needed to determine the address ranges associated with each of the logical
slots. In the example in Figure 4-3 below, the memory configuration example shown in
Table 4-8 has been used.
In this example, we first determine the memory cards that are installed in each physical
slot.
Next, we circle the corresponding memory card capacity in the second column. Note that
we circled two 16's for each 32MB memory card.
We now look for the 128MB memory card that is associated with the lowest numbered
logical slot. In our example, the 128MB card in physical slot 0, logical slot 0 is the first
and only 128MB card.
Using Table 4-9, we write the hexadecimal address range for 0 to 128MB in the first col-
umn.
Next we look for the 64MB segment of memory in the lowest numbered slot. In our exam-
ple, that is the 64MB segment in logical slot 4.
Then we look for the 16MB segment of memory in the lowest numbered slot. In our exam-
ple, that is the 16MB segment in logical slot 1, which is the 16MB memory card in physi-
cal slot 1.
Using Table 4-9, we write the hexadecimal address range for 192MB to 208MB in the first
column of our worksheet.
We continue this for each logical slot in numerical order, skipping the slots that do not
have any memory.
