Update Drivers and BIOS via PowerShell and Dell Command Update

NOTE: I used Sapien's PowerShell Studio to write this script that significantly simplified the process!

During the build process, I execute the Dell Command Update to make sure the latest drivers and BIOS version are installed. I use the script below so that it can disable the BIOS password and execute the dcu-cli.exe in either a 32-bit or 64-bit system. The BIOS password must be disabled if you want the BIOS to be updated. Also, I execute the script in two different task sequences. This allows for the BIOS to be completely updated. There are often interval BIOS updates that have to be installed first before the latest can be installed.

You can download the script from here.
