"Instructions for use"

Remove all battery and CMOS battery

press F1 to enter setup: password 1234
wait 20sec or more.
Enter any ID to hardware Id.
Press 2x space bar when asked.
Turn off the computer.
and restore your original bios .

Enjoy.

If 2x 5beep, it's normal.
I didn't do checksum but it must light up anyway.
Wait minimum 30sec before screen logo light on. Must turn on/off several times by itself.
