Image a USB stick from Linux with an environment and exe to upgrade your bios.
This project provides Linux users an easy way to create a USB stick that they can use to update their BIOS.
This project provides a script and necessary files to create a disk image that can be put onto a USB stick. A computer can boot off the USB stick which automatically runs a DOS executable. The DOS executable must be provided by the user. The DOS executable would be the BIOS updater.
For example, DELL provides a BIOS update named M4600A16.exe. This is a DOS
executable. I only have Linux on my machine, so I had to create a USB stick,
with M4600A16.exe in its filesystem, that would boot my machine into a DOS
environment. Then I could execute M4600A16.exe to update the BIOS.
I wanted an eay way to image the USB stick if another BIOS update came out. Or if I wanted to update the BIOS on another machine. Additionally, I wanted it to automatically run the BIOS updater and then reboot when it was done.
This does NOT mean the BIOS updater will run without user input. You will still have to verify that you want to go ahead with the update if it prompts you.
Copy creatediskimg.ini to options.ini.
Edit options.ini
Specify bios_exe. This is required to run. This will be the BIOS updater
that you downloaded.
Do NOT specify usb_dev if you do NOT want the script to write to your USB
stick. It will just create the disk image. And then you can image your USB
stick manually. Otherwise, you can set usb_dev = /dev/sdX, where
sdX is the device name for your USB stick. Then the script will image
your USB stick for you.
The script must be run with root privileges.
sudo ./creatediskimg --config=options.ini
The script expects 'python' to be in the path. It will run with Python 2.7 or later and Python 3.4 or later.
You can also specify the particular Python you want it to run with:
sudo python3.4 ./creatediskimg --config=options.ini
The [utils] section in the config file shows all the external utilities
that the script needs. The paths given are standard on most Linux distributions.
The script checks that if can find the utilities and it will fail before doing
anything if it cannot find one or more utilities.
You can change the path for any utility to allow the script to succeed. You may
have to change mkfs to point to the utility on your system that creates
a FAT filesystem.
The included img-files directory was bootstrapped using files from the
FreeDOS distribution. The FreeDOS website is:
