4. Extract the downloaded package. The image filename depends on your hardware model. For example, A10Q_wnos or
X10_wnos.
NOTE: After you upgrade to the latest version of ThinOS 9.1, you can only downgrade to ThinOS 8.6 or previous
versions of 9.0 or 9.1 by using the USB Imaging Tool with Merlin Images posted on the www.dell.com/support site. Once
the system is upgraded to ThinOS 9.1, if the BIOS password is set as default or if the password field is empty, then the
Secure Boot is enabled automatically. If you want to downgrade to ThinOS 8.6, disable the secure boot option in the
BIOS. If you want to downgrade to ThinOS 9.0, you must clear TPM or PTT in the BIOS.
NOTE: For a given ThinOS release, you can install only the supported packages mentioned in the corresponding ThinOS
Release Notes available at www.dell.com/support.
5. If you want to install the latest BIOS package, locate the package entry—ThinOS 9.1 <version> BIOS package <version>—
for your thin client model and click the download icon.
For information about BIOS installation, see BIOS Installation.
