I did not see a way to edit my previous post but I will answer my own questions to serve as guidance for others who may wish to perform the same process.

Yes, the CH314A will work to read the firmware from the W25R256JVEN. In the CH314 Programmer v2.21 (by Shichang Zhuo) it will be recognized as a W25Q256FV, but it will read, wipe, and verify fine. However, what will not work, is what I originally tried - running windows in a VM (VirtualBox on Linux) and passing the USB programmer through to the guest OS. This setup never resulted in a good read of the chip so I had to go directly...

I've been researching how to dump the BIOS from a Dell 5420. This Youtube video shows the exact model and uses the same chip (W25R256JVEN) as the one I am trying to read. However, I have a few questions before I proceed.

I do not have the funds for a decent hot air station setup, so I will need to read the chip directly on the board. I planned on using a CH341A programmer and the ASProgrammer software. Is this reader and software appropriate?

I did realize that the CH341A programmer package linked above uses a SOIC8 clip but since the chip package is WSON8, I will need...

Thank you! VB.Net will always hold a place in my heart... 😀...

Thank you!

Is the source code still available? I'd like to learn more about this process.
