If any anomaly of the followings is encountered —
a) CMOS data is corrupted;
b) you forgot the supervisor or user password;
c) failure to start the system due to BIOS mis-configuration
— 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 pin 2 and pin 3. Wait for a few seconds and set it back to its de-
fault setting, i.e. jumper cap on pin 1 and pin 2.
3. Plug the power cord and power-on the system.

(COM1), JP7 (COM2), JP25 (COM3), JP23 (COM4), JP26 (COM5), JP27 (COM6).
