This guide is intended to help you set up the server(s) necessary to boot a NetBSD workstation over the network. The steps this HOW-TO describe do not require you to have any OS installed on your client machine, or even a hard drive on that machine (thus the name diskless). The intent is to run NetBSD on a machine without any local storage (e.g., hard drive), although the directions in this document describe how to netboot a machine to the point where you can install NetBSD on a hard drive if you do not have any OS currently on your machine. This HOW-TO does not describe the actual install procedure, only the steps leading up to running the install tools. This HOW-TO is intended as a supplement to the official installation notes. You should read those before attempting to use this HOW-TO. If you have a small hard drive, it is still probably worthwhile to install the bootloader, a small root partition, and a small swap partition on it, as it will boot and run significantly faster than over the network. This HOW-TO is rather long in the attempt to cover as many permutations of hardware and OS as possible. If you're impatient, you may try reading the &man.diskless.8; man page. Read the introduction page(s) to determine if your hardware and boot rom version are capable of booting off a LAN.

A quick run-down of what's necessary for a new client architecture is available. Finally, even if you do not have another Unix system available for serving the diskless machine, you can use a Windows PC as a BOOTP/TFTP/NFS/FTP server. Most of the platform-dependent information in this HOW-TO still applies if you do it that way. The initial version of this HOW-TO and the hp300 section were written by Michael Wolfson. Most of the information in these pages were derived from emails sent to the NetBSD/hp300 mailing list. In particular, thanks go to: Jason Thorpe, for writing all of the diskless software on the NetBSD/hp300 end of things (and for being the NetBSD/hp300 port maintainer); YAMAMORI Takenori, for porting rbootd to SunOS, Solaris, NEWS-OS, HP-UX, and a few other OSes and for leaving a trail of documentation in his wake; Peter Maydell, for porting rbootd to Linux and providing copious documentation on the process; Klaus Klein, Rainer Kopietz, Stan Brown, and Peter Radcliffe, for figuring out how to get the NetBSD rbootd to work under FreeBSD; Wes Brown, for hints on how to configure HP-UX to use rbootd; Peter Radcliffe for additional FreeBSD and Solaris info, as well as proofreading; Lazaro Daniel Salem, for suggestions on clustering to save disk space; Curt Sampson, for writing the alpha netboot documentation; Bob Lantz, Dan Mcmahill, Reiner Buehl for detailed pmax information; And, Brian Chase, author of The VAX Network Booting HOWTO on which much of this HOW-TO is based.
