Removing a SIMM

If both of the SIMM connectors are filled and you want to install more memory (for example, if you want to replace a 4 MB SIMM with an 8 MB SIMM), one or more SIMMs must be removed before a larger SIMM can be installed. Then refer to the previous section, “Installing a SIMM,” for installation instructions. A SIMM can be removed from and installed in either SIMM connector as long as DRAMØ, the SIMM connector closest to you, is occupied. Also, you must make sure that there is a total of at least 12 MB of RAM installed.
