Administrator Guide

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 xen. The directory structure must read as C:
\inetpub\wwwroot\WYSE\xen.
To upgrade the ThinOS Lite firmware using HTTP or HTTPS server:
1. Go to www.dell.com/support.
2. Download the latest ThinOS Lite firmware and latest ThinOS Lite 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.
3. Place the extracted firmware files in the C:\inetpub\wwwroot\WYSE\xen folder, and the packages to C:
\inetpub\wwwroot\WYSE\xen\pkg on your HTTP or HTTPS server.
4. Create a xen.ini text file (using a text editor) in the C:\inetpub\wwwroot\WYSE\xen folder with the following INI
parameters:
Autoload=2 loadpkg=1 Addpkg=FR
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 is integrated into the ThinOS Lite firmware image. Installing the latest ThinOS Lite firmware image
automatically installs the latest version of these packages on the ThinOS Lite 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 Lite 2.3, 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 INI parameter chapter in Dell Wyse ThinOS Lite Admin Guide.
5. Save the xen.ini file.
6. On the ThinOS Lite client desktop, navigate to System Setup > Central Configuration > General.
7. 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 Lite 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.
8. Click OK.
9. Restart the thin client and wait until the auto-installation of packages is complete.
