        Hello, and thanks for the Bios Pragmatiko

        I'm sorry that I have to bring the subject back but I need help from you, please.

        My problem is that the bios that I downloaded from Pragmatiko (first thread) is 1KB too big, I use the Bios programming tool: EZP2010 with the 3.0 firmware. The error message in the program is: File is too long. he does not invite it.

        on the spi / bios chip is the number MX25L6405E
        but the program recognizes it as MX25L6405D.

        Chip Type SPI Flash
        Manu: MXIC
        Chip: MX25L6405D

        With Hex Editor I can open it but I do not know what I should delete to 1KB to save

            🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
            by macabook
            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
            ...

            [Problem/ Request] Bricked TongFang GK7MRFR BIOS
            by cr4zychriss
            Hello everyone,
            I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
            I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

            ASUS Zenbook Pro Duo UX8402ZA BIOS
            by pirati
            Hello everyone,

            I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

            When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

            I decided to try flashing a new BIOS, but since I didn’t want to desolder...

            Product ID: RZ09-0421
            Motherboard: CH580
            BIOS Versions I work with: 2.02 & 2.06

            Dear Forum Readers!

            I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
            I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
            The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
