Great job friend, in case the same thing happens to someone, I received the equipment without an image, I found a bios on another site with which I got a screen but a message that said boot guard verified dxe that is fail system will shutdown, I tried with your bios , it kept giving me the same message, then i wrote the 4mb file to the other chip and it worked perfectly on an inspiron 7568 2 in 1.Comment

Thanks !
For posterity : I had a Dell Inspiron 13-7359 with 2 amber 4 white, which means board or chipset issue, and it would also randomly boot and shut down soon after.
This bios fixed it.Comment

Hi everyone,
I’m working on a Dell PowerEdge R340 (Service Tag: JTMLKB2).
The iDRAC is bricked — system hangs at “iDRAC initializing,” fans at 100%, and no VGA output.
The cause is a bad firmware flash to the iDRAC SPI.
Board details:
- Model: Dell PowerEdge R340 (14G)
- iDRAC version: iDRAC9
- Flash chip: Winbond 25Q032 (32 Mbit / 4 MB)
- Location: iDRAC EEPROM near the BMC (ASPEED AST chip)
- Tool used: CH341A programmer
What I need:
- A clean, working 4 MB `.bin` dump of the 25Q032 from another R340... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hi there everyone!
I am awaiting on a CH341 programmer and a WSON 6x5 probe to dump the flash of a Dell 7320 8FC8 with Winbond 25R256JVEN chip, in the meantime I'd like to get things ready in order to maximise my chances of success. I have seen a few tools around, NeoProgrammer, Universal BIOS Backup ToolKit, CH341A Programmer, Flashrom to name some. Which one is the most recommended/suitable for this kid of application? The only one that seems to have support is NeoProgrammer New Update V2.2.0.10.
I find my self a bit confused, and I would rather getting a clean dump...09-09-2025, 01:53 AM -
Hello everyone,
I need the EC firmware dump for Dell Latitude 5420, motherboard GDF40 LA-K491P Rev 3.0 (A02).
The embedded controller is MEC5107-LJ (UE1).
The EC flash chip is W25Q80DV, 8Mbit (1MB).
I already have the 32MB BIOS dump (W25Q256JV), but my system is still not powering on — just amber blink. I suspect the EC firmware is missing or corrupted.
If anyone has this board and can share their EC dump from the 25Q80DV, I’d be very grateful.
Thank you in advance!... -
