However, you can force reboot the thin client as the image is already installed. Upgrade BIOS Prerequisites ● Depending on your thin client model, download the relevant BIOS file from www.dell.com/support. ● If you are upgrading BIOS using Wyse Management Suite, register your thin client to Wyse Management Suite. NOTE: On thin clients that run ThinOS versions earlier than ThinOS 9.1.6108, you must upgrade the OS image first, and then upgrade the BIOS after the OS image is successfully upgraded. Do not upgrade the BIOS and the OS image together. If you upgrade the BIOS and the OS image together, the BIOS upgrade is ignored, and you cannot upgrade the BIOS to the ignored version anymore. You must upgrade the BIOS to another version. 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. On the Configuration Control | ThinOS window, click the Advanced tab. 3. Expand Firmware and click BIOS Firmware Updates. 4. Click Browse and select the BIOS file to upload. 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: BIOS upgrade requires a display screen (integrated or external) without which the update fails. In this case, you cannot install the BIOS package again. You must install another BIOS version. 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 latest Dell Wyse Management Suite Administrator's Guide at www.dell.com/support. NOTE: If you have not synced the BIOS password in the Wyse Management Suite server, you can enter the current BIOS password in the Current BIOS Admin Password field to publish the BIOS settings. If you have synced the BIOS password in the Wyse Management Suite server, this field is ignored. Wyse Management Suite 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 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, modify the post behavior options. 9. Click Save & Publish Upgrading the ThinOS firmware 43

However, you can force reboot the thin client as the image is already installed.

Upgrade BIOS

Prerequisites

●

Depending on your thin client model, download the relevant BIOS file from

www.dell.com/support

●

If you are upgrading BIOS using Wyse Management Suite, register your thin client to Wyse Management Suite.

NOTE:

On thin clients that run ThinOS versions earlier than ThinOS 9.1.6108, you must upgrade the OS image first,

and then upgrade the BIOS after the OS image is successfully upgraded. Do not upgrade the BIOS and the OS image

together. If you upgrade the BIOS and the OS image together, the BIOS upgrade is ignored, and you cannot upgrade the

BIOS to the ignored version anymore. You must upgrade the BIOS to another version.

Steps

Open the Admin Policy Tool on the thin client or go to the ThinOS 9.x policy settings on Wyse Management Suite.

On the

Configuration Control | ThinOS

window, click the

Advanced

tab.

Expand

Firmware

and click

BIOS Firmware Updates

Click

Browse

and select the BIOS file to upload.

From the

Select the ThinOS BIOS to deploy

drop-down list, select the BIOS file that you have uploaded.

Click

Save & Publish

The thin client restarts. BIOS is upgraded on your device.

NOTE:

BIOS upgrade requires a display screen (integrated or external) without which the update fails. In this case, you

cannot install the BIOS package again. You must install another BIOS version.

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 latest

Dell Wyse

Management Suite Administrator's Guide

www.dell.com/support

NOTE:

If you have not synced the BIOS password in the Wyse Management Suite server, you can enter the current

BIOS password in the

Current BIOS Admin Password

field to publish the BIOS settings. If you have synced the BIOS

password in the Wyse Management Suite server, this field is ignored. Wyse Management Suite 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 thin client or go to the ThinOS 9.x policy settings on Wyse Management Suite.

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

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.

In the

Power Management

section, modify the power-saving options.

In the

POST Behavior

section, modify the post behavior options.
