A guidance how to create a bootable USB-Stick / Pendrive (incl. MS-DOS system files) to perform a BIOS update.

see also: BIOS Update per DOS-Boot-Diskette

 

Requirement

  • The Laptop-/Mainboard-BIOS must support bootable USB-Sticks - which should apply to most of all modells which are not older than 4-5 years. If an USB-Stick was recognized during the boot process, the BIOS will integrate it as a removable drive, or as a normal drive.

 

The following tools are needed:

  • Ultimate BIOS-Boot-Edition:
    - usbdos (folder contains the 3 hidden! MS-DOS system files command.com, io.sys and msdos.sys)
    - HP_USB_Disk_Storage_Format_Tool v2.2.3.exe (Hewlett-Packard's Format-Utility for USB-Sticks)
    download [1] Ultimate BIOS-Boot-Edition - 5.9MB
  • Flashtool - an executable program (.EXE as file extension), which programs the BIOS file onto the BIOS-Chip, and the BIOS file must be downloaded:
    - Mainboard, bought in its original box: from the mainboard manufacturer website, or
    - Notebook or brand PC: from the notebook/brand PC manufacturer website.
    Both files must be specially designed for the DOS Operation system! If the manufacturer offers only files for Windows, you have to risk the BIOS update either directly under Windows, or you can re-program your old BIOS-Chip, or purchase a new, programmed BIOS-Chip.

Instruction to create a bootable USB-Stick

  • Open the Ultimate BIOS-Boot-Edition and the folder boot_usb_stick.
  • Copy the folder usbdos to your hard disk.
  • Start the HP USB Disk Storage Format Tool.
  • Select your USB-Stick under Device.
  • Choose FAT-32 under File system and activate the check mark Create a DOS startup disk.
  • Insert the path to your usbdos folder under using DOS system files located at:.
  • Press the Start button and wait until the tool has formatted the USB-Stick and has copied the 3 system files.
  • Rename the filename of your flashtool and the BIOS file, if they have more than 8 characters (not the file extension!).
  • Copy your flashtool and the BIOS file onto the USB-Stick.
The DOS system files are normally invisible, because their file attribute is set to hidden. If you would like to show these hidden files, you have to enable the option: "Windows-Explorer / Tools / Folder options / View / Show hidden files and folders" and to disable the option "Hide protected operating system files".

 

Starting the BIOS-Update from USB-Stick

  • First, go into your BIOS-Setup and change the Bootsequence to USB-Stick/Drive (search for an option like Bootsequence, First Boot Device, or something similarly).

  • Insert the USB-Stick and restart your PC. If all went well - MS-DOS starts and you can see the famous DOS-Prompt (C:\>).

  • Now you can start the BIOS update. Remember: it's a good idea to backup the old BIOS version.

Happy flashing!

 

User-Comments: BIOS Boot-USB-Stick

Hello to you all. The BIOS of my Toshiba Satellite P200 does not have the USB disk or stick Boot option, but it has floppy boot possibility by an USB external floppy drive. How to make an USB stick to look like the floppy drive and having at the same time a live linux OS on that stick. Thanks.

I am stuck at C prompt after booting from USB. Can someone tell me which files need to be copied to the usb because it doesn't run the exe file. Which is the flash tool here? and also the command used to execute the bios flash?

@FJQ
You should ask a friend with experience bios knowledge, or: Make a bootable USB-Stick and copy all bios files which were inside the DOS folder (nb-bios-e1425m-10201gb.exe) onto the pendrive. Boot from pendrive and insert "GO.bat" at the command prompt. Or: use the Windows files to update the bios within Windows.

I have a Gigabyte E1425M laptop and need to update BIOS.WHP that i downloaded from gigabyte website, there is no instructions on gigabyte website or any other place on internet that I can find to get the process to update the BIOS. Can anyone help with a step by step details.

Man,thank you!! Bios update complete with success!! A was able to update my bios just as you say, but with a little tweak of mine on the last step. The thing is, my PC was booting up via pen drive, but it stopped at the DOS prompt (common problem that I saw here). I discovered that the DOS prompt doesnt know how to open/manage ".EXE" files. You will run into this problem if your board manufacturer gives you a BIOS update as a single ".EXE" file download. To be explicit, you wont know where to find our flashtool nor bios file on the last step (Copy your flashtool and the BIOS file onto the USB-Stick). So from here, what I did was extracting the contents to my bootable pen drive (SIMPLE!). Yes, just extracting! Because, you will notice that the file given by you manufacturer is a self extracting bios ".EXE" file that copy its contents to a floppy disk and creates a bootable floppy disk. So, what you need to do is, instead of extracting the contents to the floppy, do it to a temporary folder (you may create a new folder called "temp"). When I run (on a Windows7 PC) the ".EXE" file downloaded from my manufacturer website, it gives me an option to extract the files to a chosen folder. After that, the last thing is copying the files on your "temp" folder to your pen drive. Attention, if the in the process it is asked if you want to Copy or Replace any file that is already on your usb, keep your original files on the usb. And that is all, after this your usb should be ready. From here, restart yor PC booting from the usb, and the bios update process should start automatically. Just follow the on screen instructions and you should be ok. Thank you again biosflash for this magnificent tip!!

I did copy all of them, and tried. First of all, when I swithc on the laptop it does not detects anything, No recovery disc working either. its just hang. I press F@ but no response. Lastly, i tried pressinf Fn+Esc to update bios but screen balnk. No power LED blinking.

@patel
I would guess that you have to copy all of them on to the pendrive. Boot the pendrive and insert the command: flash.bat at the DOS prompt.

but my computer runs perfectly fine just wanted to update everything for the best performance I don't see how the bios chip is defective if that is the case.

@Chris1337c
This error msg could mean that your BIOS-Chip is defective.
