I have a Dell Latitude 7430 that I've written UEFI variables to and deleted the key I need to erase them. To correct this I need to dump my BIOS and manually edit out the changes and write the BIOS back to my Dell. I own a CH341A Green board with variable power adjustment and a CH341A Black board and a Ponoma Fluke Chip clip. I see three chips which may be my BIOS or from what I've read two of the chips could be the BIOS. Can anyone help me understand how Dell has designed the board and how can I dump the full contents. The chips I see are 25Q80DVSIG 25Q256JVEN 25R128JVSN. When I put the chip clip on the chip it turns green but I cannot recognize the chip in Flashrom. Has someone written a how to for my board that I can follow? Am I required to desolder the chip to read it or can I use the chip clip? Thanks in advance I'm somewhat new at this process.

Thank you hoaca388 Can I dump both of these with a CH341A and a Ponoma Clip? Do I have to do anything besides removing the CMOS battery and ensuring there is no power to the board? What is my next step after dumping? Can you recommend a good post that explains what software I should use to combine the two chips and make modifications?
