I haven't tried this yet, but from this link: http://thoughtsdaily.wordpress.com/2...ios-in-ubuntu/
they did this:
sudo apt-get updateThen, get the System ID:
sudo apt-get install smbios-utils
sudo getSystemIdYou will get an output like this: (from my Dell Optiplex 760)
Libsmbios version: 2.2.28You will only need the System ID,
Product Name: OptiPlex 760
Vendor: Dell Inc.
BIOS Version: A12
System ID: 0x027F
Service Tag: 860774J
Express Service Code: xxxxxxxxxxx
Property Ownership Tag:
go to http://linux.dell.com/repo/firmware/bios-hdrs/ and search for the System ID.
There will be multiple choices, get the one with the BIOS version you want.
Click on it and download the bios.hdr file.
To install the BIOS file, we have to activate the dell update service, (if there is no output, the service is activated)
sudo modprobe dell_rbuTell the update tool what to do:
sudo dellBiosUpdate -u -f /place/where/the/bios/is/bios.hdrYou are ready now and can restart the computer. The new BIOS will be installed at the first boot, this can take some time (it took me 5 minutes).
This way, you don’t have to struggle with a floppy disk or a Windows installation.
so if I can just extract the hdr file from the .exe then I am going to try this on my Dell Latitude D430, unless anyone has any warning against it.
