The following sections show the internal switch settings and the external connectors and pin assignments
for applications.
2.2 Switches
The KMDA-3230 Box Computer has a number of switches on the panel that allows you to configure your
system to suit your application. The table below shows the function of each of the board’s switches:
Switches
Name
Description
SW1
Clear CMOS Data Setting
3-Pin Switch
SW2
Set Power-on mode at AT or ATX
3-Pin Switch
2.2.1 SW1-Clear CMOS Data
Figure 2. 1
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. Dial the dip switch to CLEAR mode, stay for 5~6 seconds, and then revert to CMOS mode;
3. Power-On the computer, press the Del key to enter the BIOS setting and reload the optimal default
value;
4. Save and exit the Settings.
