First, install libsmbios-bin
sudo apt-get install libsmbios-binNow, you need to get the proper .hdr file. It is bundled inside those little executables Dell has on their website. So, start by downloading the latest
After trying unzip, I tried this command, and it worked:
wine O780-A13.exe -writehdrfile -nopauseCreating the file: O780-A13.hdr Now, follow these directions (as su or root):
modprobe dell_rbu dellBiosUpdate -u -f ./O780-A13.hdrNow just reboot, and wuala, an updated BIOS.
