Thank you [USER="391642"]hoaca388[/USER] 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?hoaca388

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 [FONT=Aptos]25Q80DVSIG [/FONT][FONT=Aptos]25Q256JVEN...

Hobbiest interested in dumping and modifying laptop bios for various projects. I'm looking for an information resource for my Dell 7430. How do I dump the bios? Are there multiple bios i need to dump? Do I have to mod the chip to dump? Do I cut the vcc? Do I dump with the pc powered on? Do I have to remove all power? How do I know which winbond chips are the right. To dump?...

How can I dump my bios to share here? I purchased a ch134a and I have a raspberry pi 3+. Do I need to dump via hardware or is there a way to software dump the bios?
