If you encounter the followings
a) CMOS data becomes corrupted.
b) You forget the supervisor or user password.
you can reconfigure the system with the 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. Set CMOS pins 2 and 3 to On. Wait for a few seconds and set CMOS back to its default setting,
pins 1 and 2 On.
3. Now plug the power cord and power-on the system.
