Automating Dell Vostro 330/360 BIOS Updates

Posted on

The majority of the desktops in our environment are Dell Vostro all-in-ones.  Even though this is consumer-line hardware and not subject to Dell’s OMCI tools, we purchased this model because of price and because Dell didn’t have a OptiPlex all-in-one.  The BIOS installers for these Vostros do not properly respond to the silent/unattended switches that they should support.  Fortunately there is a work-around with this simple process.

  • Extract the WINFLASH files:  Just simply double-click the installer then when it’s at the first dialog box for the upgrade, make a copy of the files from C:\ProgramData\WINFLASH.  Cancel out of the installation.
  • Create a script to run the command “winflash.exe %pathToWinFlash%\BIOS.bin /p /b /n /r“.  Note that it is extremely important that for BIOS.bin that you include the full path to the file because winflash.exe doesn’t check that its local directory contains the .bin file.
  • The restart of this will be suppressed, so remember to restart the computer after installation.

Voila!  You have now upgraded BIOS on the Dell Vostro 330 and/or 360.

    Fantastic! Only one problem though – it clears the Admin password from the BIOS and cctk won’t work on a Vostro so SOL I guess… unless you’ve got any ideas on that one?

      Hey Gary, thanks for the feedback, I’m glad that it’s helpful. Unfortunately I no longer have access to Vostro systems, so I wouldn’t be able to help you much further. Good luck though and if you figure something out, feel free to post back here so we all know!!

        Will do! I wish there was more documentation on Winflash… ;-)
