META Information This section lists the meta-information of this document. The hows, whys, location and changes to the structure of the document are documented here. The main content begins in the next chapter. The Purpose of this Document This document is to serve as a comprehensive HOWTO and FAQ collection regarding the Sun JavaStation NC and enabling the GNU/Linux OS on it. The intended audience of this document is anyone who has an interest in enabling Linux on the Sun JavaStations. The document structure is laid out to serve as either a top-to-bottom read for a newcomer, or as quick reference on a single topic for advanced users. Pointers to sample files submitted by users are included for extremely hurried readers. The author of this document is Robert Dubinski Robert is the former computer technician and UNIX systems administrator for Marquette University's Math, Statistics and Computer Science Department, where he had 125 JavaStations running Linux. These machines were all configured using the information, techniques and files presented in this document. In early 1999, Eric Brower wrote the first informal HOWTO for the JavaStation. Parts of this document are inspired by his work, and all unique information presented there have since been merged into this document. Eric's original mini-HOWTO is saved for posterity at: This HOWTO also aims to serve as a member document of the Linux Documentation Project. The LDP can be reached at: Acknowledgments Enabling Linux on the JavaStations , and allowing this HOWTO to come to be would never have been possible without the fine work of the following people: Pete Zaitcev (Primary JavaStation kernel mod author) Eric Brower (XFree mods and author of the original embedded-build HOWTO) Varol Kaptan (made available his Krups images and patches. Backported kernel support to 2.2.x series) David Miller (the original Linux/SPARC kernel porter) The Linux/SPARC kernel porters and mailing list The thousands of contributors to the Linux kernel The HOWTO author wishes to give a second thank-you to Pete and Eric for their work:
Robert Dubinski, March 2000 Pete got me going with Linux on the JavaStation in December 1998, has been the main kernel programmer adding in support for the JavaStation line, and despite his busy work schedule was nice enough to find time to answer all my email queries for help over the last 15 months. Eric worked on bringing X support to the JavaStation when it had none. He had been working on a dedicated server for the JavaStation in early 1999, and kept me informed of his progress. In mid-1999, he switched tactics and sent a working framebuffer example to test out. He also wrote the first comprehensive mini-HOWTO for the JavaStations, answered my email questions, and got me interested in the embedded solution which I employ here at Marquette. Thank-you Pete and Eric!

History 1.30 31 Oct 2001 Many major changes: restructured for better layout, new chapters added, updated files and file pointers, new master distribution location, source broken into parts, new sample files, md5sums on all sample files, overall update and proofread of materials. Thank-you very much to Simon Kuhn for donating an old Sun4 to enable more sample files be made. Thank-you also to Nate Carlson for donating sample kernels (unfortunately that info was lost during a disk crash...Nate, please contact me.). If anyone contributed items between May 31 and Oct 31 and it does not show up in this revision, please resubmit it. 1.25 30 Oct 2001 This is called the "@#!$?" release. It is called such because there were some small-mid size changes to the document which were lost in a disk failure, prior to me re-uploading to the LDP site. To give you an idea of how bad the situation was, the last version I had on backup was in Docbook SGML, while I had switched to Docbook XML many months prior. Simply put, any contributed changes or email contacts I had with contributors were lost, and are hopefully on their way back in with this release. If you contributed something, and it disappeared, please contact me immediately, and it'll get back in. --RSD 1.22 31 May 2001 Changed file links, some sample file formats, and clarified info relating to the sample files, following requests on the sparclinux mailing list. 1.20 08 May 2001 Information Refresh up to the current date, and change to GNU Free Documentation License 1.1 1.15 01 May 2001 Migrate source to DocBook XML 4.12 1.13 02 Feb 2001 Minimal Bugfixes 1.12 29 Dec 2000 Additional info on the "Fox" model 1.11 23 Nov 2000 Krups truecolor blurb, removed one acknowlegement per email request 1.1 15 Nov 2000 Numerous updates and additions revisions 1.05 16 Jun 2000 Requested Format Changes and Fixes 1.04 13 Jun 2000 Suggested Fixes and Added Requests 1.03 04 May 2000 Minor Fixes, Requests 1.02 28 Apr 2000 Small fixes. 1.01 25 Apr 2000 "Brown Paper Bag" Revision. 1.0 24 Apr 2000 First submission to the LDP. 0.9 18 Apr 2000 Continued reorganization and final merges. 0.7 15 Apr 2000 Migration from LinuxDoc DTD to Docbook DTD. 0.71 14 Apr 2000 Received word doc was forwarded inside Sun. 0.7 14 Apr 2000 Linked on Metabyte Website. 0.6 9 Apr 2000 First semi-public release. 0.4 24 Mar 2000 First move to comprehensive HOWTO. 0.2 15 Oct 1999 More notes collected and merged. 0.1 24 Jun 1999 Initial scraps put together.

In Spring 2001, discontinued their free service and moved to a fee based scheme. Given the hundreds of mirrors of LDP documents, I do not find the fees justifiable. I have changed all references in this document back to my home server.

The folks on there really do not care about my typos or server misconfigurations, so please don't trouble them. TODO List for this HOWTO As NetBSD now supports JavaStations as well, it would be good to talk about support and sample files for it too.
