MEMORY CONFIGURATION

The Mainboard lets user upgrade system memory via SIMM sockets and DIMM
sockets on the mainboard.
Four SIMM sockets (SIMM1, SIMM2, SIMM3, SIMM4) are provided for SPM, FPM
and EDO RAM SIMM and two DIMM sockets (DIMM1, DIMM2) are available for
the SDRAM or 3.3V EDO DIMM.
Note: The type of SIMM1/SIMM2 must be same.
The type of SIMM3/SIMM4 must be same.
SIMM3/SIMM4 and DIMM1 cannot co-exist.
SIMM1/SIMM2 and DIMM2 cannot co-exist.
Table 1 provides some typical memory configurations supported by the mainboard.
Onboard memory is located in two banks:
Bank 0: SIMM3 & SIMM4
OR
DIMM1
Bank 1: SIMM1 & SIMM2
OR
DIMM2
The total memory size is 8-256MB and various configuration of DRAM types in the following
