Abstract: Disclosed methods respond to detecting the receipt, by a management controller, such as a baseboard management controller (BMC), of an information handling system, of a provisioning request from a management client, by rebooting the information handling system to initiate a Universal Extensible Firmware Interface (UEFI) boot sequence that is configured to load an EFI application, referred to herein a provisioning application. A two way communication channel such as a WebSocket is established between the management client and the management controller to stream OS image data corresponding to an OS image to the management controller. The OS image data streamed to the management controller is written to an OS image partition of a boot device, after which the stored OS image may be booted to load the OS. The provisioning request may be communicated as a representational state transfer (REST) compliant (RESTful) request using, in at least some deployments, a Redfish application programming interface (API).
