CONFIGURING THE SYSTEM
__________________________________
CONFIGURATION OF MEMORY
The configuration of the memory is very flexible.
There are several combinations of DRAM types you may
consider. 1MB, 4MB or 16MB SIMM are acceptable. So, a
basic system can be equipped with fewer memory and
later more memory can be installed when upgrading the
system. The memory size is detected automatically by
system BIOS and indicated during memory test after
reset. No jumper is needed to be set for the memory
size and DRAM type.
To determine what DRAM speed rating should be
used depends 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. If zero wait
state is selected, fast page mode DRAM is needed. The
wait state setting is applied to all banks of memory.
Therefore make sure to install DRAM with the same
speed rating, or accommodate the wait state setting to
the slow DRAM type.
Because of the shadow RAM function, the 384KB
memory between 640KB to 1MB can not accessed. So,
the memory size found by the system BIOS is not equal
to the actual memory size. For example, when there is
4MB on board, the BIOS will show 3712KB.
