BOOT SYSTEM FOR DISTRIBUTED DIGITAL DATA PROCESSING SYSTEM

A distributed digital data processing system including a host and at least one node interconnected by a communications link. In response to a boot command, the node requests its boot image from the host over the communications link. The host then provides pointers to portions of the boot image to the node. The node then retrieves the portions of the boot image identified by the pointers. These operations are repeated until node retrieves the entire boot image. By having the host supply pointers to the boot image and the node perform the retrieval operations in response to the pointers, the host is freed to perform other operations while the node is actually performing the retrieval operations.
