how to update BIOS from Linux

 z2ox6w

You can click the link below to download and install the bios file in a non Windows Environment. It doesn't specifically say Linux.

Run the BIOS update utility from DOS environment (Non-Windows users)
1. Copy the downloaded file to a bootable DOS USB key.
2. Power on the system, then Press F12 key and Select "USB Storage Device" and Boot to DOS prompt.
3. Run the file by typing copied file name where the executable is located.
4. DOS System will auto restart and update BIOS while system startup screen.
5. After BIOS update finished, system will auto reboot to take effect.

Note 1: You will need to provide a bootable DOS USB key. This executable file does not create the DOS system files.
Note 2: Please make sure you suspend BitLocker encryption before updating BIOS on a BitLocker enabled system. If you don't enable BitLocker on your system you can ignore it

z2ox6w,

I do not have any information on the software to write a .exe. You may want to do a google search on making the Linux usb key bootable.
