Setting the Amount of Memory
Your computer has two types of memory: base memory and extended
memory. The base (or main) memory in the Equity 386 is set at
640KB, which is the maximum value and is recommended for most
applications. You may, however, need to reduce the main memory
(usually to 512KB) to run certain software applications that require a
smaller main memory size.
The value you set for the extended memory depends on the total
amount of memory available in your computer above the 1MB of
main memory. This amount consists of any additional RAM you
have installed on the main system memory card and on any memory
expansion card you may have installed.
