36 <p>
37 The following systems are known to be very stable overall. Just about all the
38 core hardware is supported in these systems, and there are very few outstanding
39 stability issues at this time.

71 At present, only the Newport (XL) graphics framebuffer is supported in
72 Linux. Therefore on systems with other framebuffers, you will need to
73 use serial console.
74 </li>
75 <li>
76 The Challenge S has its RJ-45 connector on a daughter board (Mezz)
77 linked with an unsupported SCSI adapter, a WD33C95A. In order for this
78 network connector to function, this SCSI bus needs to be activated,
79 however it is not yet supported by Linux. As a result of this, the
80 Challenge S can only get network connectivity via its AUI connector.
81 </li>
82 <li>
83 Indigo2 EISA Support isn't very well
84 tested and may not work with all hardware. Hardware that it is known
85 to function with is listed, and as more compatible hardware is
86 discovered, it will be added. Please note that hardware requiring DMA
87 support is currently not functional. This includes EISA/ISA-based
88 soundcards. EISA Video cards requiring an x86-compatible BIOS are also
89 not functional.

128 <p>
129 The systems listed here are known to run Linux, however in many
130 cases, there are known stability issues and major gaps in the hardware
131 support. In short, it will be a rough and bumpy ride.

174 IP28 Indigo2 Impact support (classified as an Indigo2 system w/ an
175 R10000 Processor) is <e>very experimental</e>. Most of the work was
176 done by Peter Fuerst, who maintains patches on his <uri
177 link="http://www.pfrst.de/download.html">website</uri>. This kernel is
178 <e>not</e> intended for stable, day-to-day use. The Indigo2 IP28 system
179 suffers from an issue known as <e>Speculative Execution</e>, a feature
180 of the R10000 Processor that is problematic on machines that are <e>Non
181 Cache Coherent</e>, such as the IP28 Indigo2 and on R10000/R12000-based
182 IP32 O2 systems. Details on the nature of Speculative Execution, and
183 the issues it poses to the Indigo2 can be found at the following URLs:

219 Octane support in Linux should be regarded as broken. Stanislaw
220 Skowronek did the reverse engineering and bring up. <uri
221 link="http://www.linux-mips.org/~skylark/">His page</uri> is available
222 but has not been updated since October 2006.
223 </li>
224 <li>
225 The serial ports on the Octane currently only support 9600 baud rate,
226 8-bits, no parity, 1 stop bit. Other baud rates do not currently work
227 at present.
228 </li>
229 <li>
230 Dead due to issues porting the IRQ handling to newer Linux kernels.
231 Help is welcome.

243 <section>
244 <body>
245
246 <p>
247 Just about all of these systems are totally unsupported at the kernel level &ndash;
248 making a full Linux system totally impossible. Little is known about a lot of
249 the systems listed here &ndash; therefore any support in the near future is highly
250 unlikely. You may wish to keep an eye on the <uri
251 link="http://www.linux-mips.org">Linux/MIPS website</uri> for any news of ports
252 &ndash; either that, or start your own. :-)

275 As with most systems, there is quite wide array of peripherals that one can
276 obtain for Silicon Graphics systems. While a lot of these work in IRIX, Linux
277 support is a bit touch-and-go on some of these items. The following table
278 lists the support for each device.

333 <title>Cobalt Servers &ndash; Stable</title>
334 <section>
335 <body>
336
337 <p>
338 The Cobalt servers are a set of machines all based around the QED RM523[01]
339 CPU. They came in two varieties, the RaQ &ndash; a rackmounted model, and the Qube,
340 a small desktop model (1ft. cube). The big difference between these systems
341 and the SGI systems above, is that these systems are <e>little endian</e>
342 (<c>mipsel</c>) as opposed to <e>big endian</e> (<c>mips</c>).
343 </p>
344
345 <p>
346 These were also sold under an OEM arragement to other companies, examples of
347 this are the Gateway Microserver (Qube 2) and the Seagate NasRaQ (RaQ 2).
