SCCM Dell BIOS Updates: Automating Driver Downloads

If you manage a large Dell hardware estate through SCCM, keeping BIOS versions and drivers current across every model in your environment is a genuinely tedious manual task — there are community PowerShell scripts that automate discovering your Dell hardware models and downloading the latest available BIOS/driver packages for each.

The General Approach

These scripts typically work by querying your ConfigMgr hardware inventory for distinct Dell model strings present in your environment, then using Dell’s Catalog/driver download APIs (Dell publishes machine-readable catalogs specifically for this kind of automation) to pull the latest matching BIOS and driver packages for each model found, saving you from manually visiting Dell’s support site per model. Review the full script from the source linked in this post’s resources before running it in your environment – confirm it targets the correct Dell catalog endpoint (these have moved/been renamed periodically) and test the download/packaging step against a small subset of models first, since a large estate could mean a lot of downloaded content if something’s misconfigured.

Once Downloaded

Package the downloaded BIOS/driver content as ConfigMgr Packages or Driver Packages per model, and deploy via a maintenance task sequence or Task Sequence step targeted at the relevant device collection for each Dell model.

One Thing Worth Checking Before You Run This in 2026

The general approach here — querying ConfigMgr hardware inventory for Dell model strings, then pulling the latest BIOS/driver packages from Dell’s machine-readable catalog — is still current practice. The specific catalog file has moved on, though: Dell retired CatalogPC.cab in late 2025, so if the script you’re running still points at that filename, update it to the current catalog cab (Dell’s replacement is commonly referenced as CatalogIndexPC.cab/DellSDPCatalogPC.cab in current community scripts) before relying on it — an old hardcoded URL will silently fail to find updates rather than error out clearly.
