    Request: Full BIOS dump for ASRock Z790-CX (DDR5)

    Hello everyone,

    I’m looking for a full raw 16 MB BIOS dump for an ASRock Z790-CX (DDR5) motherboard.

    The board powers on (fans spin, RGB lights on, RAM LEDs active), but there is no display output and the VGA and BOOT LEDs stay lit.
    I’m using an Intel i9-14900KF CPU (14th gen), and it seems the BIOS version on my board doesn’t support it yet. I tried to flash the official ASRock BIOS file (renamed .ROM → .BIN) directly using my RT809H programmer, but it didn’t work — monitor stays on but with black screen, so I believe the ASRock update file is not a complete image.
    I need a complete BIOS image (bin dump) that can be programmed directly into the SPI chip. Any help or shared dump from the same board (or compatible ASRock Z790 model) would be greatly appreciated.
    Thanks in advance!

      Have you tried with a known good PCIe GPU? The 14900KF doesn't have integrated GPU...
      Your motherboard supports 14900KF since initial BIOS version 12.09

      BIOS from ASRock website is full BIOS image including Descriptor, GbE, ME and BIOS regions, the problem is elsewhere

      * If Gigabit Ethernet doesn't work, hope you have a BIOS backup before you flashed the BIOS from ASRock website with your programmer, MAC address has to be transferred as you have Intel® I219V Gigabit LAN

          Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
          by Ahari
          Hi all,

          This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

          I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

          I...

          Full BIOS Dump for ASRock H310M-HDV Rev 1.02 (MX25L12873F)
          by khanhtq0
          Hello everyone,

          I'm looking for a full BIOS dump (.bin) for the ASRock H310M-HDV Rev 1.02 motherboard. The BIOS chip is a MX25L12873F (128Mb / 16MB).

          I’ve already tried flashing the official BIOS from ASRock (version 1.40 and 3.30), but those are Instant Flash versions and don’t include the full SPI image (e.g. Intel ME Region, Descriptor, etc.). After flashing, the board powers on only when I short PS-ON to ground, and it fails to generate Vcore and 2.5V. Other rails like 1.05V and RAM voltage are present.

          I suspect the original Intel ME and descriptor...

          I need a BIOS dump for the Samsung S49CG934SU monitor
          by Habble7
          The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

          Suspected Cause:
          I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

          I’m kindly requesting a clean and unlocked BIOS dump for the following HP laptop, as it’s bricked after flashing SP152727. The system now keeps rebooting, and the original issue was an Administrator / Power-On Password that I can no longer access.😏

          by Citymin
          Hi all,

          My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
          The charging red LED lights up, but the charging screen doesn't show any indication.
          When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
          (I've tried removing the battery and resetting the device, but the issue persists.)
