Dynamically Update BIOS on Think Products with SCCM

NOTE: What follows is a brief look at what is possible and not necessarily recommended for everyone.  Hopefully someone finds it useful.


Earlier at MMS this year, a fantastic session on modern driver management in OS deployments was presented by Kim Oppalfens and Tom Degreef.  This method and what it entails can be found here.

I was inspired by their session and wanted to see if this could work with Lenovo's BIOS updates in a similar manner.  The workflow is basically the same, with the key piece being the overridable task sequence variable in the Download Package Content step called OSDDownloadDownloadPackages.


Here's the layout of the Task Sequence:
