Upgrade BIOS using WMS

Explains how to upgrade the BIOS on ThinOS devices, use WMS or the Admin Policy Tool after the ThinOS image has been successfully updated.

1. Open the Admin Policy Tool on the device or go to the ThinOS 10.x policy settings on WMS.
2. On the Configuration Control | ThinOS window, click the Advanced tab.
3. Expand Firmware and click BIOS Firmware Updates.
4. Click Browse and select the BIOS file to upload.
5. From the Select the ThinOS BIOS to deploy dropdown menu, select the BIOS file that you have uploaded.
   After a successful upload, the BIOS package appears under the BIOS Firmware Updates list in WMS with the correct Platform Type associated with the firmware file.
6. Click Save & Publish.
   The device restarts. BIOS is upgraded on your device.

   NOTE:For more information about the latest BIOS version, see the latest Dell Wyse Management Suite Version 5.x Release Notes at Support | Dell.

   NOTE:BIOS upgrade requires a display screen (integrated or external) without which the update fails. In this case, you cannot install the BIOS package again. You must install another BIOS version.

   If a power adapter is not connected on any ThinOS Mobile Client, the BIOS update fails. After the power adapter is connected, you must reboot to trigger the BIOS update again.
