Release Notes

To upgrade the ThinOS firmware using HTTPS server:
1. Ensure that you have downloaded the latest ThinOS firmware and latest ThinOS packages that corresponds to your thin
client model. If the firmware and packages are in the form of a compressed self-extracting (.EXE) or zipped file (.ZIP), then
extract the files.
2. Place the extracted firmware files in the C:\inetpub\wwwroot\WYSE\wnos folder, and the packages to C:\inetpub
\wwwroot\WYSE\wnos\pkg on your HTTPS server.
3. Create a wnos.ini text file (using a text editor) in the C:\inetpub\wwwroot\WYSE\wnos folder with the following INI
parameters:
Autoload=2 loadpkg=1 Addpkg=TCX,FR,horizon
The option Autoload=2, ensures that the thin client uses the firmware installed on the server to upgrade, only if the
firmware on the thin client is older than the version on the server. The option LoadPkg specifies how to update the external
packages. If LoadPkg is not in the statement, it will inherit the value of AutoLoad.
Base package and the PCoIP package are integrated into the ThinOS firmware image. Installing the latest ThinOS firmware
image automatically installs the latest version of these packages on the ThinOS client. If you set AutoLoad=1 LoadPkg=0,
the firmware is checked, but the packages are not checked. The packages check is performed after firmware check. From
ThinOS 8.3, the external packages update mechanism is changed. Some packages are default, and loaded according to value
of LoadPkg. For example RTME. Some packages need additional parameter AddPkg to add. For example, FR, Horizon, and
TCX. The option AddPkg is for adding packages. It depends on the value of LoadPkg. For more information about the INI
parameter usage, see Dell Wyse ThinOS INI Reference Guide.
4. Save the wnos.ini file.
5. On the ThinOS client desktop, navigate to System Setup > Central Configuration > General.
6. In the General tab, enter the IP address of the file server or directory. For example: https://IPaddress/wyse.
NOTE:
You can also use DHCP option tags 161 and 162 to configure the ThinOS client, file server and path information.
You must create these options on your DHCP server, configure them with the correct server information, and enable the
DHCP server scope in your environment.
7. Click OK.
8. Restart the thin client and wait until the auto-installation of packages is complete.
