I am trying to update my BIOS:

$ sudo dmidecode -s bios-version

With a newer one: 2.6.0. I went to this page Dell Precision System BIOS, 2.6.0

After downloading the file WS390-020600.BIN, here is what it states:

$ ./WS390-020600.BIN --help
Usage: WS390-020600.BIN [options]
  --help                  Print this text.
  --version               Print package versions.
If no options, update the BIOS.


$ ./WS390-020600.BIN --version
Dell BIOS Update Installer 1.2

./WS390-020600.BIN: 60: ./WS390-020600.BIN: ./flash: not found

Does anyone knows where this flash command can be found ?

Update: it looks like this is a self-extracting archive (need bash as per comment in header).

$ head -30 WS390-020600.BIN
    tail -n +`awk '/^__ARC__/ { print NR + 1; exit 0; }' $0` $0 | gzip -cd >$_PRG

So the flash command should have been auto-generated, however the above command does not appear to be running as original author intended. I do not see anything wrong with the command though.


The extractor actually does extract the flash binary, but it immediately removes it after trying to run it. You're seeing the "not found" error because you're missing the 32-bit libraries needed to run it. On Ubuntu 14.04, I was able to get a Dell BIOS updater to run by installing these libraries with:

$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install libc6:i386 zlib1g:i386
