CONFIGURATION OF MEMORY
The configuration of the memory is very flexible. It can install
256KB , 1MB or 4MB SIMM modules are acceptable. There are several
combinations of DRAM types you may consider. So, a basic system can
be equipped with fewer memory and the system can be upgraded by
installing the extended memory. The different configurations of memory
is illustrated at the next page.
There are totally two banks of DRAM. The memory size is
detected automatically by system BIOS. This detection is performed
during memory test and the size is indicated after reset. No jumper is
needed to be set for the memory size and DRAM type.
To determine what DRAM speed rating to be used is depended
on the system speed and wait state. The highest performance is
accomplished by using zero wait state, but high speed DRAM has to be
used.
The wait state setting is applied to two banks of memory.
Therefore make sure to install DRAM modules with the same speed
rating, or accommodate the wait state setting to the new DRAM type.
