    BIOS flashing techniques?

    Last time I flashed a BIOS was about 4 years ago and I used the old school method - A floppy loaded with DOS files and the downloaded BIOS file. I'm a bit hazy on the details now.

    Can anyone here refresh my memory on this or suggest a modern method. I had one of those BIOS programming cards that hooked up to a serial port or a USB port but I never got it to work properly and it seems to have been lost in my house moving.

    I still have a bunch of floppy drives and cables but I only ever flashed old socket A and 370 chips because I feared bricking the BIOS.

    Short of buying a new BIOS chip what do you guys do?

    It all depends on what needs updating but generally if it's dead I remove it from the board to program. If it's on a working device, it all depends on how the BIOS update is provided as to how it's programmed, some update from Windows executable some USB.

      you can use a program called Rufus to create a bootable dos usb stick.
      then use it just like you used a floppy disk

        If the board allows physically removing the chip (aka PLCC/DIP socket), then simple. I crank out another board, a 8GB WDC with a 98SE install on which I copy the BIOS file, and then boot to DOS. I use Uniflash 1.40 most of the times, except on newer boards (P4 and up usually) where I use the DOS variant of flashrom.

        Gigabyte B75M-D3H
        Core i5-3470 3.60GHz
        Gigabyte Geforce GTX650 1GB GDDR5
        16GB DDR3-1600
        Samsung SH-224AB DVD-RW
        FSP Bluestorm II 500W (recapped)
        120GB ADATA + 2x Seagate Barracuda ES.2 ST31000340NS 1TB

          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...

          X270 - Bios flashing help
          by Timeeez
          Hello everyone,

          I am still a beginner and want to learn more about flashing bios. First of all, thank you very much for the tutorials made on this forum it helps a lot.

          Lets get straight to the point. When I try to flash the bios of my Lenovo X270 it restarts several times and always returns to the bios that was there at the beginning. When I get the bios from someone on the forum and write it to the bios chip, I always have the same serial numbers. I have the feeling that the pc is reflashing itself. Where could this come from? How to avoid this problem?

          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
          by zenius
          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

          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...
