Hello,
I'm having the following issue: I tested this BIOS and the system boots up without any problem, but when the operating system starts, the BIOS gets updated and the computer stops turning on, only showing the message "BIOS CORRUPTED."
Has anyone else experienced this issue?

Rev: 2.0 (A01)

Hello everyone,
I have a Dell Latitude 5420 (tested without HDD) and I’m running a diagnostic tool such as Aiken Workbench. The problem is that the tool detects the onboard LAN card, but it shows the message:"no working driver for it"
and the test result is NO Driver.
Interestingly, when I install Windows, the LAN card works perfectly fine, which confirms that the hardware itself is okay. I have tried multiple cables and diagnostic environments, but the result is the same.
For comparison, I have a BIOS dump from a working unit and another from the problematic unit. The file sizes are identical. I suspect the issue might be related to a missing or corrupted PXE/UEFI network driver module in the firmware.
My questions:- Has anyone experienced this issue before?
- What are the recommended steps to add the proper LAN driver to a diagnostic/WinPE environment, or to safely repair the firmware?
- If no solution can be found, I would appreciate it if any expert who knows how to fix this fault could contact me privately to suggest the right approach.
Thank you in advance for your help.Leave a comment:

Hi guys, I have a latitude 5420 here, I've done a few but this one is proving to be an issue.
Chip resoldered, laptop boots but NVME not detected, from a bit of reading this could be a corrupt ME region?
Can anybody help please?
I have uploaded the original locked dump, so if somebody could remove the admin password and repair the ME I would be forever grateful, thank you.

As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows
