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.
