Important notes
This section contains information about firmware upgrade and system configuration that you need to know before using ThinOS
Lite version 2.6.
Firmware upgrade and downgrade notification
The Local display 16-bit color option is removed from Wyse 3010 and 3020 zero clients.
System configuration and deployment
● ThinOS BIOS policy can be configured using Wyse Management Suite Console, Wyse Management Suite group INI, Wyse
Management Suite advanced settings and FTP INI. Dell recommends that you use any one of the methods to configure the
BIOS policy. Setting the BIOS policy simultaneously using different methods may cause a policy mismatch, and the device
reboots repeatedly. This reboot loop issue is observed when you select the reboot immediately option in the BIOS policy
settings section on the Wyse Management Suite console.
● All the installed packages are deleted when you update the ThinOS Lite version between major releases—2.5 to 2.6—using
FTP, WDM, or Wyse Management Suite.
Solution for updating firmware using FTP and WDM—Ensure that you have set the PKG install parameters in the WNOS.ini,
and the pkg files are uploaded in the directory. After the device reboot, the packages are re-installed automatically.
Solution for updating firmware using Wyse Management Suite—Wyse Management Suite App policy works only once after
the policy is created. The deleted package cannot be reinstalled using the same policy. Dell recommends that you create a
new App policy to install the package after the firmware update is complete.
● WDM vulnerability is fixed in this release. You must configure either the DHCP or the DNS option/record of the WDM server
fingerprint to automatically fetch and validate the fingerprint before checking in to the WDM server. However, there is no
impact to the ThinOS Lite device functionality if you do not to configure the fingerprint validation environment. For more
information about how to set up fingerprint using WDM, see the Dell Wyse ThinOS Lite Version 2.6 Administrator's Guide at
www.dell.com/support.
