Introduction and Overview
This document describes the changes made to the NetI module, supplementing the original documentation of the module.
Technical Details
Zero-Configuration networking issues
The NetI module has been updated to address a few issues which arose after changes were made in Select 3 to introduce Link-Local address configuration. The NetI module will now ignore any link-local addresses as candidates for the automatic network map construction. Link-local addresses have 16 bits which describe the network and may co-exist with other non-link-local addresses. They are not suitable for use as a NetI network address.
Machine types
The machine types returned by the machine peek operation have been updated to reflect the modern systems. A reservation has been made for the Iyonix (although the Iyonix presently claims to be a RiscPC system). The A9 has also been added to the list (and is reported correctly).
The full list of machine types is (original list in PRM 2-635):
