If any anomaly of the followings is encountered —
a) CMOS data is corrupted;

— it is suggested that the system be reconfigured with default values stored in the ROM BIOS.
To load the default values stored in the ROM BIOS, please follow the steps below.
1. Power-off the system and unplug the power cord.
2. Put a jumper cap on JP5’s pin 2 and pin 3. Wait for a few seconds and set JP5 back to
its default setting, i.e. jumper cap on pin 1 and pin 2.
