Before you install SIMMs, check the following guidelines to ensure that the memory modules will work properly:
Cl Be sure to use SIMMs that operate at a 70ns (nanosecond) access speed. Each SIMM must have the same access speed.
LI Use the correct SIMM configuration to add the amount of memory you want. See the tables on page
Once you have the correct SIMMs, you or your dealer can install them in your computer. If you are going to install them yourself, follow the instructions below.
Installing Memory Modules
There are 12 SIMM sockets on the main system board. The sockets are organized in six banks consisting of two sockets each. Each socket can contain one memory module.
You must fill the sockets in any bank you use. Since each bank has two sockets, you must install two SIMMs to fill the bank. One socket in each bank is labeled with an “L” and the other is labeled with an “H.” For example, Bank 3 is made up of socket 3L and socket 3H. Therefore, if you use Bank 3, you must install one SIMM in socket 3L and one SIMM in socket 3H.
The following tables show all the possible SIMM configurations for the Equity 386SX PLUS. Do not install SIMMs in any other configuration. If your computer came with 2MB of memory, use the first table; if it came with 1MB, use the second. Keep in mind that either 1MB or 2MB of memory is already soldered directly onto the main system board.
