Dell ThinOS 10.x 2502, 2505, 2508, and 2511 Release Notes

Enhanced Mode

Enhanced Mode is a privileged operating state that grants advanced system access, including the App Builder feature.

To enable Enhanced Mode, do any of the following:

• Log in to WMS as an administrator and select Groups & Configs > <Select a group> > Edit Policies > ThinOS10.x > Advanced > Desktop Mode > System Operating Mode, click Enable Enhanced Mode.
• Open APT on the device and select Advanced > Desktop Mode > System Operating Mode, click Enable Enhanced Mode.

For more information about Enhanced Mode, see App Builder User's Guide and ThinOS 10.x 2502, 2505, and 2508 Administrator Guide at Support | Dell.

App Builder

The App Builder allows you to create Customer Installed (CI) application packages using uploaded Binaries and Debian packages. These packages can be deployed to ThinOS devices using WMS or APT.

Customer installed (CI) applications can be installed and used only in Enhanced Mode, and are not supported in Appliance Mode.

To enable App Builder Mode, do any of the following:

• Log in to WMS as an administrator and select Groups & Configs > <Select a group> > Edit Policies > ThinOS10.x > Advanced > Desktop Mode > System Operating Mode, and enable App Builder Mode.
• Open APT on the device and select Advanced > Desktop Mode > System Operating Mode, and enable App Builder Mode.

ThinOS 10.x Compatibility Checker

ThinOS 10.x Compatibility Checker allows you to boot on a nonsupported device and run a compatibility check. This tool identifies if the current device is supported by ThinOS 10.x and provides a report on compatibility issues.

ThinOS 10.x Compatibility Checker is designed to evaluate whether your hardware is compatible for running ThinOS 10.x. It performs two types of checks to guide your installation decisions:

• Mandatory checks—Verify that the hardware meets the minimum requirements to install ThinOS 10.x.
• Optional checks—Provide additional insights into hardware capabilities, helping you decide whether to proceed or adjust the hardware setup.

For more information about compatibile Dell and non-Dell platforms, see ThinOS 10.x Hardware Compatibility List document at Support | Dell.

Exploring ThinOS 10 in Live Boot

The ThinOS 10.x Compatibility Checker supports a live boot option, which allows you to explore ThinOS 10.x and verify specific hardware and peripheral functionality before installation.

Converting IGEL OS to ThinOS 10.x

ThinOS 10.x 2508 supports converting IGEL OS to ThinOS 10.x, registering an IGEL device with Universal Management Suite (UMS), using the Scan for Devices feature to automatically detect IGEL devices within the same subnet as the UMS server or within a specified IP range.

Alternatively, you can register the device using a One-Time Password (OTP) generated from the UMS console.

For more information about converting IGEL to ThinOS 10.x, see ThinOS 10.x 2502, 2505, and 2508 Migration Guide at Support | Dell.

DHC to ThinOS 10.x Config tool

DHC to ThinOS 10.x Config tool is a GUI-based feature that helps in migrating configuration settings from DHC to formats compatible with ThinOS 10.x.

For more information about exporting DHC policies using WMS, see ThinOS 10.x 2502, 2505, and 2508 Migration Guide at Support | Dell.

BIOS Common Configuration

ThinOS 10.x 2508 supports BIOS Common Configuration, which acts as a centralized settings page that consolidates all BIOS settings that are supported across all ThinOS 10.x devices. It enables users to view and configure BIOS settings ensuring standardized system configurations across the ThinOS 10.x using the same Active Directory in WMS.

To access the BIOS Common Configuration settings in WMS, go to Advanced Settings > BIOS Common Configurations > Dell Supported Devices BIOS Settings.

For more information about BIOS Common Configuration, see ThinOS 10.x 2502, 2505, and 2508 Migration and Administrator Guide at Support | Dell.

Support for 32 GB storage and 4 GB RAM

ThinOS 10.x 2508 expands compatibility to devices with 4 GB RAM and 32 GB flash, enabling support for both VDI and browser-based use cases.

The following are the key highlights:

• Enables real-time RAM monitoring on the client and continuously checks available free RAM.
• If available RAM drops below the defined threshold, users receive an alert to save any unsaved work and close unnecessary applications to avoid performance issues or data loss.
• Administrators can configure a minimum RAM threshold that must be met before launching new VDI or browser sessions.
• If RAM is below the threshold at launch, users are notified, and an alert is displayed on the WMS server.
• For CI applications, only low-memory notifications are supported (launch continues).
• During ThinOS 9.x to ThinOS 10.x upgrades, WMS displays a warning to administrators:
• Devices that are upgraded from ThinOS 9.x to 10.x, having less than the recommended RAM size (8 GB), may have few limitations.

For more information, see ThinOS 10.x 2502, 2505, and 2508 Administrator Guide at Support | Dell.
