Try again with Password Generator.

Use an External US Keyboard (QWERTY), use SHIFT Key for Uppercase letters, Hold left CTRL Key then Press ENTER Key twice.

I m gonna try now , but i think my programmer kill the bios memory . I read it with CH341A without making the 3.3 V modification and as far as i read the max voltage for this memory is 4.5v

Now i get an orange light when i press the POWER button. I order a new memory . it should be in couple of days...is weird because i am still able to READ/WRITE on the programmer but when i solder it back on motherboard, orange light is coming ON when i press POWER button.

I try to power the motherboard without the memory and it behaves the same...

I ll wait the new memory and make sure i ll do the 3.3V modiication .

Thanks

Man, Uou are Legend!

All working OK

No pass

Much appreciated!

So summed up, even if i read/write memory without the voltage hack on the programmer, everything is working but anyway i will do the hack just in case for further preparation.
