3.
Main Board Data Utility
To use this diskette, first boot from this diskette, then a “Microsoft Windows 98 Startup Menu” prompt you to 
choose the testing item.  Follow the instructions on screen to proceed.
NOTE: 
This program contains a readme.txt file.   This readme.txt file will introduct each test utility and its 
functions.
IMPORTANT:
If this diskette is not bootable, do the following actions before you use it:
1.
Do system transfers.
2.
Copy HIMEM.SYS to A:\.
3.
Copy EMM386.EXE to A:\.
Panel ID Utility
There is an EEPROM in the inverter which stores its supported LCD type ID code. If you replace an LCD with 
one of a different brand or use a new inverter, the ID information in the inverter EEPROM should be updated.
Follow the steps below to see the LCD Panel ID:
1.
Follow the instruction on screen to read current or to set new LCD Panel ID code.
NOTE: 
When you set a new LCD Panel ID and the new LCD is not yet enabled (to function), so connect an 
external CRT to see the program execution process.
NOTE: 
 Make sure the new ID code you choose corresponds with the LCD brand and type. If you write a wrong 
ID into inverter, just reboot and re-execute the program and input the correct ID code.
2.
Restart computer - the new LCD should work normally.
NOTE: 
If LCD cannot display after change ID code, make sure you write the correct ID code, or try 
reconnecting the LCD FPC cable connectors.
Thermal and Fan Utility
The system is equipped with sensors to protect against system overheating. By setting System and processor 
thermal thresholds, the system can turn on the cooling fan or shut down automatically when temperatures 
reach the defined threshold parameters.  This utility will test fan, processor thermal and system thermal.
Main Board Data Utility
This utility will display Main Board Data (MBD) which include header informaiton, product name, manufacture 
name, UUID (Universally Unique IDentifiers) and serial number.   This fucntion can display and create MBD 
data as well as store those information to LCD inverter EEPROM (not flash ROM).
