You need only 5 pins-KS03/KSI4/KSI5/KSI6/KSI7 and need to connect them with RT809F.

Remember,
KSI4=CS
KSI5=CLK
KSI6=DIN
KSI7=DO
KS03=GND

With the above information you can easily find out the pins of RT809F but where to connect on mb kbd connector-you need to find out in schematics.

Re: bios password dell latutide 3540

Dear @nabilgo, i dont use vertyanov and dont have much idea about it. I use svod where you can download the pinout file for particular mb from online database. i think it should be almost similar procedure for your programmer as well.

As far as clean kbc dump is concerned, please let us know the mb part no like LA-XXXX and Rev no.
