Really two questions:
1. Is there an ISO protocol for booting devices on a LAN (similiar to
IP's BOOTP)?
2. What ISO document to I purchase to get its description?
Thanks

Because the OSI model of an information system and a network is very broad and general, services as specific as booting of a diskless workstation are not really addressed directly. Some ISO standards and protocols do provide facilities that are related, however. The ISO Manufacturing Messaging Service (MMS) is a general-purpose remote device control service, although it was developed for industrial robots. It supports a download/upload facility for a "Virtual Manufacturing Device". Combined with "program invocation management" services, a BOOTP-like service could be provided. However, MMS is an application-layer service and its protocol implementation requires the full OSI stack to be in operation for a connection to be established, and booting of that stack is undefined. Probably closer to your intent, the evolving ISO network management standards provide for "configuration management" from a control center of a population of "managed objects" on the network; this includes creation and deletion of those objects, and control operations on them, by a remote management agent. The most important managed objects are the layers of the stack themselves, so it would fit well to define a management bootstrap action that begins with a short or null stack, brings up a tiny management agent, responds to a "Create" request (PT_CREATE CMIS request) for a managed object corresponding to a system with a local action to boot that system and initialize a full stack, and then resume management services over the full stack. The bootstrap procedure itself would be beyond the scope of the management action; it might, for example, be a proprietary link-level boot protocol based on a distinguished LSAP selected by the vendor (or it might in fact be BOOTP itself :). However, I don't think the management standards have evolved that far yet. Perhaps your description of more specific requirements for a boot protocol might get things going. > 2.
