Driver CABs Understanding Delta Reports

Driver CABs Understanding Delta Reports

The driver CABs are updated based on the release schedule and in response to customer questions, we are providing a way to see what has changed in the new release of driver CAB with respect to previous driver CAB (does new driver CAB contains all applicable latest drivers?, etc.). The "Delta Report" is the answer to these questions.

"Delta Report" is the report built by Dell engineers and are the basis for finding applicable latest driver candidates for new driver CAB release.

"Delta Report" as the name suggests, contain the difference between the applicable latest set of drivers available on Dell Drivers and Downloads and the previous driver CAB. Thus enabling customers to understand the changes in the new driver CAB. A "Delta Report" provides the following information:

  • Contents of previous driver CAB.
  • Changes since previous driver CAB.
  • Highlight incremental changes.
  • Applicable driver releases for the new driver CAB.
Note: Applicability of a driver for new driver CAB releases are decided on various factors like- which driver supports more devices, is a release INF installable or Operating System Deployment ready, etc.

Release of the "Delta Report" will align with the release schedule i.e. all new driver CAB release hence forth will have "Delta Reports" associated. Any customer can navigate to a "Delta Report" by accessing links associated to a driver pack on the Driver CAB landing/Index page.
