    Thank you so much, [USER="237374"]SMDFlea[/USER]! You're the best.

    I was able to dump the BIOS, and I've attached it here. Is this correct?

    Two notes: I actually have two of these motherboards. One with a broken BIOS (I think--it won't POST), the other with a locked BIOS. I don't know which one this is. But they're both the same mobo model.

    I'm not sure what the issue is with the BIOS. Is there like a standard firmware I can flash to it? Thanks for all your help.SMDFlea...

    Thanks so much for your response. Any advice on how to identify which one of the chips is the BIOS chip?

    Based on this [URL="https://www.dell.com/support/manuals/en-us/latitude-14-7410-2-in-1-laptop/lati_7410_sov/latitude-7410-statement-of-volatility"]statement of volatility from Dell[/URL], it looks like the one I pulled off (UV32) was the HDMI controller. And it looks like the BIOS chip is the UE1 (MEC5107K-D4-LJ), which is on the bottom of the board. I found a [URL="https://drive.google.com/file/d/1uoA6fTaxQYCj_H0BskiagKxRRgZDTLCK/view"]schematic of the board...

    Hi there,

    I have a Dell Latitude 7410 with a corrupted BIOS (I assume).

    Motherboard: LA-J261P Rev 1.0
    Service Tag: 3LRHQ73

    BIOS Chip I'm working with is a GD25Q20CT

    Attached is the bad bin.

    I've tried writing other binaries to the new chips I have, but the files have all been the wrong size.

    I need a good bin for that chip so I can get the laptop working again. Would love it to have no BIOS password.

    I'm new to BIOS stuff, so I don't know much and might be off in my understanding of things. Any help...

  • Hey there, I'm Squatty95 from Utah, US. I'm trying to learn more about programming/fixing computers with broken BIOS chips. Been doing some form of tech repair for about 2 years now, and working on getting better at board-level repair.

    Thanks for the great community.
