39 The exact requirements will largely depend on what you intend to use the machine
40 for and how you wish to go about installing Gentoo. The following table should
41 give you a rough idea.

70 <title>A Note about serial consoles</title>
71 <body>
72
73 <p>
74 If you lack an appropriate Framebuffer, you will be required to use serial
75 console. Serial console programs for linux include <c>minicom</c> and
76 <c>xc</c>, and for Windows, <c>HyperTerminal</c> and <c>Tera Term Pro</c>. If
77 you are running Windows, and intend to use HyperTerminal, it is advised that
78 you seek out an updated client from the program's website instead of the one
79 installed by default. An upgraded client provides much better serial support
80 than the default one installed by Windows.

90 As an aid to the project, a <uri
91 link="http://stuartl.longlandclan.hopto.org/gentoo/mips/">hardware support
92 database</uri> has been set up. This support database is intended to provide a
93 quick and easy way to determine how well certain configurations are supported.
94 The system also allows people to contribute their comments and kernel configs.

107 The following systems are known to be very stable overall. Just about all the
108 core hardware is supported in these systems, and there are very few outstanding
109 stability issues at this time.

157 At present, only the Newport (XL) graphics framebuffer is supported in Linux.
158 Therefore on systems with other framebuffers, you will need to use serial
159 console.
160 </p>
161
162 <p>
163 The Challenge S has its RJ-45 connector on a daughter board (Mezz) linked with
164 an unsupported SCSI adapter, a WD33C95A. In order for this network connector
165 to function, this SCSI bus needs to be activated, however it is not yet
166 supported by Linux. As a result of this, the Challenge S can only get network
167 connectivity via its AUI connector.
168 </p>
169
170 <p>
171 Indigo2 EISA Support is <e>highly</e> experimental. It isn't very well tested
172 and may not work with all hardware. Hardware that it is known to function with
173 is listed, and as more compatible hardware is discovered, it will be added.
174 Please note that hardware requiring DMA support is currently not functional.
175 This includes EISA/ISA-based soundcards. EISA Video cards requiring an
176 x86-compatible BIOS are also not functional.

219 The O2 RM7000 Processor support is limited in Linux currently, as it requires a
220 fairly recent kernel version (>2.6.7), and has several notable issues. The
221 first issue is a problem with scsi at the moment, making the internal disks
222 unusable at the current time. The Level 3 (Tertiary) Cache is also disabled
223 due to there being no support for this cache in the linux kernel.
224 </p>
225
226 <p>
227 Please be aware that this note only applies to the official SGI RM7000 running
228 at 350MHz, not the 600MHz RM7000 that can be assembed using an RM5200 board.
229 These "modded" CPU modules for O2 systems are not supported/tested, although,
230 in theory, they should be functional, but may suffer from the same problems
231 listed above.

245 cases, there are known stability issues, and major gaps in the hardware
246 support. In short, it will be a rough and bumpy ride.

320 IP28 Indigo2 Impact support (classified as an Indigo2 system w/ an R10000
321 Processor) is <e>very experimental</e>. Most of the work is currently being
322 done by Peter Fuerst who maintains patches on his <uri
323 link="http://home.alphastar.de/fuerst/download.html">website</uri>. This
324 kernel is <e>NOT</e> intended for stable, day-to-day use. The Indigo2 IP28
325 system suffers from an issue known as <e>Speculative Execution</e>, a feature
326 of the R10000 Processor that is problematic on machines that are <e>Non Cache
327 Coherent</e>, such as the IP28 Indigo2 and on R10000/R12000-based IP32 O2
328 systems. Details on the nature of Speculative Execution, and the issues it
329 poses to the Indigo2 can be found at the following URLs:

382 Octane support in Linux should be regarded as experimental. Support for this
383 particular machine from SGI has been progressing quite well and the Linux
384 kernel functions reasonably well. The current status for this system may be
385 found on <uri link="http://helios.et.put.poznan.pl/~sskowron/ip30/">Stanislaw
386 Skowronek's page</uri>. Wider support in Gentoo for this system will be
387 available in the future, so watch this space closely for more details.

400 Just about all of these systems are totally unsupported at the kernel level --
401 making a full Linux system totally impossible. Little is known about a lot of
402 the systems listed here -- therefore any support in the near future is highly
403 unlikely. You may wish to keep an eye on the <uri
404 link="http://www.linux-mips.org">Linux/MIPS website</uri> for any news of ports
405 -- either that, or start your own. :-)

428 As with most systems, there is quite wide array of peripherals that one can
429 obtain for Silicon Graphics systems. While a lot of these work in IRIX, Linux
430 support is a bit touch-and-go on some of these items. The following table

502 <title>Cobalt Servers -- Stable</title>
503 <section>
504 <body>
505
506 <p>
507 The Cobalt servers are a set of machines all based around the QED RM523[01]
508 CPU. They came in two varieties, the RaQ -- a rackmounted model, and the Qube,
509 a small desktop model (1ft. cube). The big difference between these systems
510 and the SGI systems above, is that these systems are <e>little endian</e>
511 (<c>mipsel</c>) as opposed to <e>big endian</e> (<c>mips</c>).
512 </p>
513
514 <p>
515 These were also sold under an OEM arragement to other companies, examples of
516 this are the Gateway Microserver (Qube 2) and the Seagate NasRaQ (RaQ 2).

598 The Qube 2700 was the first of this whole subarchitecture. Unfortunately, it
599 lacks a serial port, making installation at present, damn near impossible.
600 We're looking into ways we can support this system, but as none of the
601 developers have access to one of these machines, we have no way to test our
602 efforts. You may wish to have a look at <uri
603 link="http://www.metzner.org/projects/qube/">Jan Metzner's page</uri> for more
604 information.
