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

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

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

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

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

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

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

383 <li>
384 Octane support in Linux should be regarded as experimental. Support for
385 this particular machine from SGI has been progressing quite well and
386 the Linux kernel functions reasonably well. The current status for this
387 system may be found on
388 <uri link="http://www.linux-mips.org/~skylark/">Stanislaw Skowronek's
389 page</uri>. Wider support in Gentoo for this system will be available
390 in the future, so watch this space closely for more details.
391 </li>
392 <li>
393 The serial ports on the Octane currently only support 9600 baud rate,
394 8-bits, no parity, 1 stop bit. Other baud rates do not currently work
395 at present.

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

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

492 (1) Work has begun on porting the ImpactSR to the Indigo2 Impact (IP28)
493 workstation. At the moment, it's early days, and the driver is not functional
494 yet, but this may change in the coming months.<br/>
495 Likewise with Extreme graphics... a few people were starting to look into
496 writing drivers for this chipset. Nothing has been released yet, but we may
497 see something in the not too distant future.<br/>
498 We will update this page if such a driver is released.

506 <title>Cobalt Servers -- Stable</title>
507 <section>
508 <body>
509
510 <p>
511 The Cobalt servers are a set of machines all based around the QED RM523[01]
512 CPU. They came in two varieties, the RaQ -- a rackmounted model, and the Qube,
513 a small desktop model (1ft. cube). The big difference between these systems
514 and the SGI systems above, is that these systems are <e>little endian</e>
515 (<c>mipsel</c>) as opposed to <e>big endian</e> (<c>mips</c>).
516 </p>
517
518 <p>
519 These were also sold under an OEM arragement to other companies, examples of
520 this are the Gateway Microserver (Qube 2) and the Seagate NasRaQ (RaQ 2).

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