Abstract: A computer booting apparatus includes a computer processor, a computer memory coupled to the computer processor, and a communication port coupled to the computer processor. The computer processor is configurable for operation in a host mode and a device mode. The host mode connects to an external computer processor and an external computer memory via the communication port, checks for a new image file or a revised image file stored in the external computer processor or the external computer memory, and loads the new image file or the revised image file into the computer memory. The device mode boots a device via the communication port using the new image file or the revised image file.

Abstract: In one aspect, a first device may download at least one disk image and then provide the disk image to second and third devices through a fourth device that controls connections to the second and third devices. The first device may then run computer diagnostics concurrently on the second and third devices through the fourth device and using the image provided to each of the second and third devices. In some examples, communication between the devices may occur using USB ports.
