Thank you.

I have programmed this patched bin file to the chip and booted the system, the password is still there and when I type any letters and press enter then this screen comes ask to press any key. After pressing any key it ask to enter the key shown with a Hardware ID. Is there anything else I need to do? Please advise.

Please check images

Kind regards

"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.
