ULTRIX Remote Installation Service
Introduction
The ULTRIX Remote Installation Service (RIS) allows to install the ULTRIX operating system and the ULTRIX Workstation Software over the network.
The system manager uses the remote installation service (ris) utility to transfer the ULTRIX subsets from the installation media to a directory on the installation server processor. This directory is the network kit.
The server processor must be running the ULTRIX Version 2.0 or higher operating system and should have a minimum of available disk space, e.g. 30 Mbytes for ULTRIX V2.0.
The RIS server must have access to a suitable load device for tape media, e.g. a TK50 or a 9-track magnetic tape drive.
All network bootable processors are supported as network installation clients.
The ris utility performs remote installation services which install system software to a client machine through the TCP/IP local network.
History
RIS was introduced with ULTRIX V2.0 and carried on to the last ULTRIX version 4.5.
From ULTRIX/RISC V3.0 (the first version to support MIPS processors) onwards you could even have "mixed architecture" RIS:
