If you are upgrading BIOS using Wyse Management Suite, register the thin client to Wyse Management Suite.
About this task
NOTE: On thin clients that run ThinOS versions earlier than ThinOS 9.1.6108, you must upgrade the OS image first, and then upgrade the BIOS after the OS image is successfully upgraded. Do not upgrade the BIOS and the OS image together. If you upgrade the BIOS and the OS image together, the BIOS upgrade is ignored, and you cannot upgrade the BIOS to the ignored version anymore. You must upgrade the BIOS to another version.
Steps
Open the Admin Policy Tool on the thin client or go to the ThinOS 9.x policy settings on Wyse Management Suite.
On the
Configuration Control | ThinOS window, click the
Advanced tab.
Expand
Firmware and click
BIOS Firmware Updates.
Click
Browse and select the BIOS file to upload.
From the
Select the ThinOS BIOS to deploy drop-down list, select the BIOS file that you have uploaded.
Click
Save & Publish.
The thin client restarts. BIOS is upgraded on your device.
NOTE: For more information about the latest BIOS version, see the latest Dell Wyse ThinOS Operating System Release Notes at
www.dell.com/support.
NOTE: Ensure that you connect the power adapter to the Wyse 5470 Thin Client before updating the BIOS. If you do not connect the power adapter, the BIOS update fails. In this event, you must connect an external power source and reboot the device twice to install BIOS.
