2.14 MEMORY INSTALLATION
The mainboard lets user add system memory via SIMM sockets on the mainboard.
On-board memory is located in two banks: Bank 0 - SIM1 & SIM2, and Bank 1 -
SIM3 & SIM4. DRAM Configuration "Table-Free"
is supported on this board. See Fig 2.
User can install either 1/2/4/8/16/32/64MB SIMM (72-pin) in each SIMM
socket. Note that all SIMM modules in a bank must be the same capacity.
SIMM speed required for best performance depends on the CPU speed, which
requires 70ns SIMM.
