J4 - CLEAR CMOS DATA

J4 is used to clear the content of the CMOS Data in the RTC (build in PIIX4 chip).

MEMORY CONFIGUARTION

The mainboard lets user upgrade system memory via DIMM sockets on the
mainboard. On board memory is located in four banks: Bank 0 - 3. Two DIMM
sockets are provided for EDO DRAM or Synchronous DRAM. Table 4 provide the
typical memory configurations supported by the mainboard.
The maximum memory size is up to 256MB (SDRAM) or 512MB (EDO). The size
of each DIMM can be 8MB, 16MB, 32MB, 64MB or 128MB.
