Every page on this index requires an active XBOX GDK for Console Development NDA. All pages are hidden from the primary sidebar navigation. Entries below are listed by title only and are not linked; NDA-cleared readers can reach them via the GDKX. ## About this section The **NDA Topics** tab collects every confidential XBOX GDK console development page in a single tab so authors and readers with NDA access can see the full surface at a glance. Pages are grouped into sections that mirror the tabs where the topics live in the rest of the documentation: * **Home** — dev kit setup, dev kit settings, and studio-wide configuration. * **Build** — console features (audio, memory, storage), core graphics features, game principles, and ATG engagement. * **Tools** — PIX, shader compiler, command-line, DevHome, hix, and other console tool pages. * **API References** — GDK graphics API reference headers and hidden system/tools API groups. *** ## Home Confidential pages from the **Home** tab of the documentation — everything needed to set up, activate, and configure XBOX dev kits. ### Setup and install #### Concepts | Page | Description | | ------------------------- | ------------------------------------------------------------------------------------------------------- | | Product permissions | Grant users, groups, and dev kits access to a product via Partner Center sandboxes. | | Deployment | Deployment types (Push, Run from PC, Streaming Install) and tools (XBOX Manager, xbapp, Visual Studio). | | Emergency Offline Updates | Perform an EOU factory reset from USB when a dev kit won't boot. | | Unexpected reboots | Diagnose why an XBOX dev kit rebooted or shut down unexpectedly. | | Universal Error Messages | Common Universal Error Messages (UEMs) on XBOX dev kits and how to resolve each one. | | Remove Gold Sharing | Reset console privileges to clear Gold Sharing from a dev kit. | | XBOX One X Dev Kit tips | Tools, updates, scripting, and front-panel tips for XBOX One X Dev Kits. | | Console modes | Approximate other XBOX platforms via console mode switching. | #### Dev kit settings | Page | Description | | ----------------------- | ------------------------------------------------------------------------------------- | | Retail ↔ Developer Mode | Switch an XBOX dev kit between Retail Mode and Developer Mode. | | Configure settings | Profiling Mode, Sandbox ID, and idle timeouts via DevHome, xbconfig, or XBOX Manager. | | Flash OS recovery | Enroll for automatic OS recovery updates or manually apply a recovery image. | | Set a host name | Give a dev kit a friendly host name so tools survive IP changes. | #### Studio-wide configuration | Page | Description | | -------------------------- | --------------------------------------------------------------------------------- | | Recover multiple consoles | Run parallel OS recoveries against many dev kits from one PC. | | Automatic recovery updates | How automatic OS recovery updates work, and how to change the update policy. | | Unattended setup script | Author unattended-setup scripts for OOBE, per-boot configuration, or ad-hoc runs. | *** ## Build Confidential pages from the **Build** tab of the documentation — console features, core graphics features, game principles, and Microsoft engagement checklists. ### Console features Hidden NDA pages that live inside otherwise-public Build groups.
