        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.

                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.

                      [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                      by zenius
                      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                      [Bios Password Unlock Request] [Dell OPTIPLEX SFF PLUS 7020] [8FC8 method]
                      by overclocker1786
                      Hello I have a dell optiplex SFF plus 7020 with a password that I recovered from e-waste. It is possible to get the password removed via the bios patch method? I managed to dump the 32MB bios chips and would like help patching it to MFG mode so I can clear the password.

                      Thanks.

                      Dell 9010 MT BIOS Update Always Fails
                      by mikeybass
                      Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...
