Configure Memory

Your board comes with three DIMM sockets, providing support for up to 768MB of main
memory using DIMM modules from 8MB to 256MB. For 66MHz host bus CPUs use 12ns or
faster DIMM modules; for 83MHz host bus CPUs use 8ns modules.

Note: Always install memory modules in the order prescribed in this table.

DIMM Modules HAVE to be inserted in following way: First DIMM3

then DIMM2/DIMM1.

Clear CMOS

In some cases the CMOS memory may contain wrong data, follow the steps below to clear
CMOS memory.

1. Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5. This jumper

can be easily identified by its white colored cap.

2. Then put the jumper back to 1-2 to allow writing new of data into the CMOS memory.
