It is highly recommended all files are backed up prior to updating the BIOS on any computer! If you have any questions, please contact endpointmanagement mit. Computer Requirements Supported OS: Only this one task sequence is needed to deploy BIOS updates to all currently supported Dell computers listed below. The task sequence will only install the correct BIOS to the related model. This task sequence is only set to work on Dell computers. If it gets deployed to a different vendor nothing will actually install.
You may see an error message that the task sequence failed as the computer is not supported. If you have multiple vendors in your department you can exclude the non-Dell computers when deploying this task sequence to your collection.
If the task sequence is deployed to a Dell computer that is not currently supported for a BIOS upgrade, BitLocker will be suspended if enabled, the computer will restart, and BitLocker will be re-enabled if previously suspended. Again these computers can be excluded from the collections you are deploying the task sequence to. Dell Supported Models as of May 3, Additional models will be added as the become available from Dell. Important Notes The update requires a restart which will happen automatically 60 second countdown before restarting.
