Dell Wyse ThinOS Version 8.6 and ThinOS Lite 2.6 Operating System Release Notes

PDF

Firmware upgrade and downgrade

  • On Wyse 5070 Extended thin client, the AMD firmware is upgraded to a newer version. If you want to downgrade ThinOS from 8.6 to 8.5.1, you must shut down and boot the thin client again. If you do not shut down and reboot, a black screen is displayed on the monitor that is connected to the AMD GPU port. Also, the AMD DP port sequence is updated.
  • On Wyse 5070 thin clients, the Bluetooth firmware is upgraded to a newer version from ThinOS 8.5_108. If you want to update the thin client with the Bluetooth module from ThinOS version 8.5_107 to 8.5_108 or later, Dell recommends that you disconnect the power cable and connect the power cable again before you reboot.
  • ThinOS 8.6 stores the installed packages (except base and pcoip) in the hidden partition. When you downgrade ThinOS firmware to previous versions, and upgrade the firmware to 8.6 again, the ThinOS device reinstalls the stored packages from the hidden partition. You can delete the package to clean the backup data from the device.
  • When you use a file server to update BIOS for Wyse 5060 and 3030 LT thin clients, the BIOS update progress bar disappears after the BIOS update process is complete, and the system reboots after one minute. You must not manually reboot the thin client. During reboot, a black screen is displayed for one minute, and then the device resumes the BIOS update.
  • From ThinOS version 8.6, the 16-bit desktop color option is removed from Wyse 3010 and 3020 thin clients.
  • From ThinOS version 8.6, the Merlin images include both RTME and Horizon packages.
  • From ThinOS version 8.6, the DP audio is disabled by default on Wyse 3040 thin client.
  • You must install the JVDI package to use Cisco Jabber.
  • If you push Merlin images on Wyse 5010, 5040, and 7010 thin clients with 4 GB or higher flash size, the RTME and Horizon packages are formatted.
