    Re: HP Elitebook 820 G2 bios needed

    I figured it out. The writing problem that i was having was caused by my soic clip making a poor connection. I will let you know the results after i am able to flash the chip.

        I'd recommend not using a SOIC clip but rather desoldering the chip to read it out of circuit.

                      Hi Everyone,

                      is there any flashrom software for Windows 10 64bit?

                        Re: HP Elitebook 820 G2 bios needed

                        Is there a Tutorial how to backub bios dump?

                        You need SPI programmer for that (for example CH341A or raspberry pi, using flashrom software).

                        Where can I download the software_

                                    File does not contain Intel Engine firmware...

                                    Read bios chip again and verify.

                                        But did you verify aswell? Simply reading again is not enough.
