Table 1-3 lists the possible memory configurations. 1. 4. 1 Rules for Adding Memory · · · Use only one type of SIMM in a given bank. [. . . ] For example, for a total memory of 8 MB, install two 4-MB SIMMs into the sockets marked S5 and S4 (bank 0) or S3 and S2 (bank 1). You can not use an 8-MB SIMM alone for an 8-MB memory.
