For warning security mode, the following warning messages are displayed:
The server address does not convert to http, if WDM server is set as https.
● In the previous scenario, If WDM server is configured without HTTPS, and local WDM server address is specified in HTTPS,
then the system converts it to HTTP address.
● In the current scenario, the system does not convert the WDM server address to HTTP.
Manual discovery is removed from WDM. In the WDA tab, the Manual discovery method option is removed.
Firmware signature
Firmware signature feature was introduced in ThinOS 8.3.1 for better firmware security. From ThinOS 8.4 release, firmware
signature verification is added to enhance firmware security.
Salient features
● By default, signature verification is required on firmware downgrade/upgrade process.
● Provision to downgrade from 8.4 firmware to 8.3 firmware without signature. For example, earlier to ThinOS 8.3.1 release,
the firmware downgrade is prohibited by default.
● New INI parameter verifysignature=no is introduced to enable user downgrade firmware. For example:
autoload=101 verifysignature=no. For more information about using INI parameters, refer to the latest Dell Wyse
ThinOS INI Reference guide.
The following scenarios are allowed without need of using INI parameters:
○ Upgrade from 8.3.x firmware to 8.4 firmware.
○ Upgrade or Downgrade between 8.3.x and/or earlier firmware.
○ Upgrade or Downgrade between 8.4 and later firmware.
