5. From the Select the ThinOS BIOS to deploy drop-down list, select the BIOS file that you have uploaded.
6. Click Save & Publish.
The thin client restarts. BIOS is upgraded on your device.
NOTE: When you use the BIOS upgrade feature for the first time, the BIOS is downloaded even if the existing BIOS
version is the same version that is uploaded.
If you are upgrading BIOS on the Wyse 5470 Thin Client, ensure that you have connected the device to the external power
source using the power adapter. If you do not connect the power adapter, BIOS update fails. In this event, you must connect
the power adapter and reboot twice to install BIOS.
Edit BIOS settings
Prerequisites
If you are using Wyse Management Suite, ensure that you have registered the thin client and synchronize the BIOS admin
password. For more information about using the Sync BIOS Admin Password option, see the Dell Wyse Management Suite
v2.1 Administrator's Guide at www.dell.com/support.
If you are using the Admin Policy Tool, ensure that you enter the current BIOS admin password in the Advanced > BIOS
section.
Steps
1. Open the Admin Policy Tool on the thin client or go to the ThinOS 9.x policy settings on Wyse Management Suite.
2. In the Configuration Control | ThinOS window, click the Advanced tab.
3. Expand BIOS and select your preferred platform.
4. In the System Configuration section, modify the USB ports and audio settings.
5. In the Security section, modify the administrator-related configurations.
6. In the Secure Boot section, enable the secure boot option. If enabled, you cannot disable it using Admin Policy Tool or Wyse
Management Suite. Secure Boot can be disabled only in the BIOS setup window.
7. In the Power Management section, modify the power-saving options.
8. In the POST Behavior section, enable or disable the MAC Address Pass-Through feature. This option is applicable only to
the Wyse 5470 Thin Client.
9. Click Save & Publish
NOTE:
If the thin client does not have a BIOS admin password, you can set the password using Admin Policy Tool or
Wyse Management Suite. In this scenario, the client reboots first to apply the BIOS admin password and other BIOS
settings take effect after the second reboot.
NOTE: Changing BIOS password using Select Group, irrespective of the parent or child group, is not supported.
