@toxstoxs - For (Macronix aka MCIX) MX25L6473E Download this package - http://s000.tinyupload.com/index.php?fil...695330485827902
Use - CH341A v1.31(1.4) (CH341AFree) - choose 8MB/64Mbit - then read, verify, and save once you get "Chip and buffer or main memory match"

You can also try MX25L6465E ID in 1.30 and 1.34

Or ASProgrammer 1.41 has the exact ID if you want to use that instead - https://github.com/nofeletru/UsbAsp-flash/releases/

Should i use the snap tool i received with the programmer to "lock on" soldered chip or.. should i remove the bios chip from the Mainboard?

@Lost_N_BIOS

Yes, you use the clip tool, here's some guides to show you how
https://www.bios-mods.com/forum/Thread-G...341A-programmer << Same as one directly below, but with all images expanded/visible at once
[GUIDE] Flash BIOS with CH341A programmer

https://weborus.com/guide-flash-bios-spi...ini-programmer/

Guide is pretty clear to me but..
Just one question...
if the bios will be 100% error free read from the programmer, is it sure 101% that has no corruption bit?
i do not have any "safe" source to compare it with. (beside the extracted bios file)
Once i have the file, will you be able to understand if it's a clean 100% file that can be modded and flashed again?
@Lost_N_BIOS

Something strange happen...
as you see from picture, i'm quite sure all is correctly connected and oriented but...
as soon as i connect the snap tool flat cable to programmer, the red power light fade out and the programmer desappear from windows.
Clear symptom of a kind of short circuit connection.
where is my mistake?









@Lost_N_BIOS

@toxstoxs - sorry for delay, I just came across your post!! All looks setup correctly, so either short in your cable or bad programmer, OR you need to maybe remove that jumper, OR maybe leave power connected to board (or removed)
Cable should be connected inside programmer before you get started, and now that you know correct position if that PCB is not soldered to the pins, you can leave out the PCB part.

Hey guys .
I would need an Hp Elitedesk 800 G1 TWR BIOS modification for Nvme boot.Previously, another motherboard was damaged due to the clip., so I would rather desolder the BIOS chip.
Is anyone making the change for me? Thank you.
