Administrator Guide

4. Add the two MIME types. Use .INI and . for the associated extension elds.
5. Apply the settings and close the IIS admin console.
Installing IIS creates the default directory C:\inetpub\WWWroot, which is known as the WWW root. In the WWWroot directory,
create a folder WYSE and a sub folder wnos. The directory structure must read as C:\inetpub\wwwroot\WYSE\wnos.
To upgrade the ThinOS rmware using HTTP or HTTPS server:
1. Sign in to the Dell Digital Locker.
2. Download the latest ThinOS rmware and latest ThinOS packages that corresponds to your thin client model. If the rmware
and packages are in the form of a compressed self-extracting (.EXE) or zipped le (.ZIP), then extract the les.
3. Place the extracted rmware les in the C:\inetpub\wwwroot\WYSE\wnos folder, and the packages to C:\inetpub\wwwroot
\WYSE\wnos\pkg on your HTTP or HTTPS server.
4. Create a wnos.ini text le (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 rmware installed on the server to upgrade, only if the rmware
on the thin client is older than the version on the server. The option LoadPkg species 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 rmware image. Installing the latest ThinOS rmware
image automatically installs the latest version of these packages on the ThinOS client. If you set AutoLoad=1 LoadPkg=0,
the rmware is checked, but the packages are not checked. The packages check is performed after rmware 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.
5. Save the wnos.ini le.
6. On the ThinOS client desktop, navigate to System Setup → Central Conguration → General.
7. In the General tab, enter the IP address of the le server or directory. For example: https://IPaddress/wyse.
NOTE: You can also use DHCP option tags 161 and 162 to congure the ThinOS client, le server and path
information. You must create these options on your DHCP server, congure them with the correct server
information, and enable the DHCP server scope in your environment.
8. Click OK.
9. Restart the thin client and wait until the auto-installation of packages is complete.
