Abstract: Examples of electronic devices are described herein. In some examples, an electronic device includes a basic input/output system (BIOS) and a processor. In some examples, the processor is to receive an enrollment message for a function of the electronic device from a server, and send the enrollment message to the BIOS. In some examples, the BIOS is to store the enrollment message in a BIOS memory. In some examples, the BIOS is to verify the enrollment message in response to a function activation request from the processor. In some examples, the processor is to enable the function based on a function activation response from the BIOS.

Abstract: An example apparatus can receive a DMA request from a device, where the DMA request comprises an address and an ID of the device that uniquely identifies the device and wherein the device is a bus mastering device. The example apparatus can access a range of addresses using the ID of the device. An example apparatus can determine whether the address is in the range of addresses and can process the DMA request responsive to verifying that the address is in the range of addresses.
