Dell ThinOS 10.x Migration Guide

BIOS setting configuration

Explains how to configure BIOS on ThinOS devices by registering the device, setting a BIOS password, and using WMS or Admin Policy Tool to apply and publish changes for secure, standardized management.

Prerequisites

If you are using WMS, ensure that you have registered the device and synchronize the BIOS admin password. The WDA stores the current BIOS password to unlock the BIOS and apply the required changes. For more information about using the Sync BIOS Admin Password option, see the Dell Wyse Management Suite Administrator's Guide at Support | Dell.
If you have not synced the BIOS password in the WMS server, you can input the current BIOS password in BIOS policy to publish BIOS settings. If you have synced the BIOS password in the WMS server, the Current BIOS Admin password option in the BIOS policy is ignored. WMS server uses the synced BIOS password to publish BIOS settings.
If you are using the Admin Policy Tool, ensure that you enter the current BIOS admin password in the Advanced > BIOS section.

Steps

Open the Admin Policy Tool on the device or go to the ThinOS 10.x policy settings on WMS.
In the Configuration Control | ThinOS window, click the Advanced tab.
Expand BIOS and select your preferred platform.
In the System Configuration section, modify the USB ports and audio settings.
In the Security section, modify the administrator-related configurations.
In the Power Management section, modify the power-saving options.
In the POST Behavior section, modify the post behavior options.
Click Save & Publish.

NOTE:If the BIOS does not have a password and you set a new one, or if you change the BIOS password using a select group, a reboot is required for the new password to take effect, while other BIOS setting changes are applied after a second reboot.

NOTE: If you enable Set Admin Password, set a new BIOS password, and then reboot the thin client, the new password is automatically synced to the WMS server. However, if you enable Set Admin Password, set the password, and then disable the option before rebooting, the BIOS password is cleared and reset to empty.

NOTE: On ThinOS clients, the Current BIOS Admin Password option is always blank, and the Set Admin Password option is always disabled. These options do not have any impact on the functionality.
