    MSI MPG B550 Gaming WiFi Edge IO bios

    Hi guys,

    I had this one for repair and discovered that the IO controler (nuovoton) was dead (shorted). Replaced it and flashed the main bios using my programmer (the usb method was not working the LED flashed for 5" and stoped) but the motherboard is still dead, no power although 3.3V at JFP1 and no LED activity.

    There is a small MXIC 25V2033F next to the IO controller which I believe could be corrupt.

    Is it possible to find a dump?

    thank you in advance,

    BR,
    George

      You probably found another solution in the meantime, but nevertheless:
      I dumped my memory of a non working edge board. It is the same as the one posted here: Link

          What should I do after having flashed a BIOS?
          by mkdj
          Dear all,

          I did my first laptop repair related to a BIOS issue. Laptop is a Lenovo ThinkPad T480, and was not booting. With my brand new programmer, I did a back-up of the current not working BIOS, erased the BIOS chip, and flashed this dump: https://www.badcaps.net/forum/troubl...83#post3686683

          Now the laptop works fine, I can access BIOS and boot on a USB drive. But I read stuff about DMI, and...

          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
          by Bloodhoundje
          Hi everyone,

          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

          I have desoldered the bios chip (GigaDevice...

          ASUS TUF GAMING Z790-PLUS WIFI - BIOS Help
          by grimacelord
          Hello,

          I have spent the last hour on this and I guess this is just over my head, so here I am.

          I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.

          The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.

          Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...

          Alienware Aurora R15 accidentally flashed with XPS 8960 BIOS
          by drux
          Hi,
          I've had an ssd that was previously used on dell xps 8960 and then it was installed in Alienware Aurora R15(intel version). On first windows boot in R15 windows started bios update and loaded bios for xps 8960(r15 and xps8960 essentially have same motherboards).

          Now it has xps 8960 bios that looks different from alienware bios and when I'm trying to run bios update files for R15, I get unsupported platform error.

          These models have AMI/Aptio BIOS.

          Tried to edit product info with DMI Edit to change values back to Alienware R15, but it does not want...
