Turn off the system.2. Short pin 2 and pin 3.3. Return jumper to pins 1 and 2.4. Turn on the system. The BIOS is now reset to its default settingTable 2.3: CMOS clear (JP4)*3.0 V Battery on Clear CMOS* default setting2.7 Installing DIMMsThe procedure for installing DIMMs is described below. Please followthese steps carefully. The number of pins are different on either side ofthe breaks, so the module can only fit in one way. DIMM modules havedifferent pin contacts on each side, and therefore have a higher pin density.1. Make sure that the two handles of the DIMM socket are in the“open” position. i.e. The handles remain leaning outward.13 Chapter 2
