33 swift 1.4 Items in <brite>Red</brite> are currently <e>Unsupported</e> in
34     Gentoo/MIPS at this time. This means Linux does not run on this
35     system/CPU at the current time, or the specific piece of hardware
36     is unsupported in the kernel.
37     </note>
38    
39     <note>
40     Items in <c>Blue</c> are considered <e>Highly Experimental</e> at this time.
41     This means the system can boot Linux, but either is unstable, or Gentoo/MIPS
42     has not been tested on it yet. In regards to hardware, it means the specific
43     piece of hardware either works to some extent, or is untested.

324     <b><c>(1)</c></b> If you lack an appropriate Framebuffer, you will be required
325     to use serial console. Serial console programs for linux include <c>minicom</c>
326     and <c>xc</c>, and for Windows, <c>HyperTerminal</c> and <c>Tera Term Pro</c>.
327     If you are running Windows, and intend to use HyperTerminal, it is advised that
328     you seek out an updated client from the program's website instead of the one
329     installed by default. An upgraded client provides much better serial support
330     than the default one installed by Windows.
331     </impo>
332    
333     <impo>
334     <b><c>(2)</c></b> The Challenge S has its RJ-45 connector on a daughter board
335     (Mezz) linked with an unsupported SCSI adapter, a <c>WD33C95A</c>. In order
336     for this network connector to function, this SCSI bus needs to be activated,
337     however it is not yet supported by Linux. As a result of this, the Challenge
338     S can only get network connectivity via its AUI connector.
339     </impo>
340    
341     <impo>
342     <b><c>(3)</c></b> Indigo2 EISA Support is <e>highly</e> experimental. It isn't
343     very well tested and may not work with all hardware. Hardware that it is known
344     to function with is listed, and as more compatible hardware is discovered, it
345     will be added. Please note that hardware requiring DMA support is currently
346     not functional. This includes EISA/ISA-based soundcards. EISA Video cards
347     requiring an x86-compatible BIOS are also not functional.
348     </impo>
349    
350     <impo>
351     <b><c>(4)</c></b> The IP22 Serial Driver is non-functional in the 2.6 kernel,
352     so while the 2.6 kernel will boot on IP22 systems, if you lack an appropriate
353     framebuffer, then you will be unable to see any output on the main console.
354     Hopefully this driver will be fixed soon.
355     </impo>
356    
357     <impo>
358     <b><c>(5)</c></b> IP28 Indigo2 Impact support (classified as an Indigo2 system
359     w/ an R10000 Processor) is <e><c>very experimental</c></e>. Most of the work
360     is currently being done by Peter Fuerst, and he maintains patches on his
361     website at <uri>http://home.alphastar.de/fuerst/download.html</uri>. This
362     kernel is <e><brite>NOT</brite></e> intended for stable, day-to-day use.
363     The Indigo2 IP28 system suffers from an issue known as <e>Speculative
364     Execution</e>, a feature of the R10000 Processor that is problematic on
365     machines that are <e>Non Cache Coherent</e>, such as the IP28 Indigo2
366     and on R10000/R12000-based IP32 O2 systems. Details on the nature of
367     Speculative Execution, and the issues it poses to the Indigo2 can be found
368     at the following URLs:

379     <b><c>(6)</c></b> The O2 RM7000 Processor support is limited in Linux currently,
380     as it requires a fairly recent kernel version (>2.6.7), and has several notable
381     issues. The first issue is a problem with scsi at the moment, making the
382     internal disks unusable at the current time. The Level 3 (Tertiary) Cache is
383     also disabled due to there being no support for this cache in the linux kernel.
384     <br /><br />
385     Please be aware that this note only applies to the official SGI RM7000 running
386     at 350MHz, not the 600MHz RM7000 that can be assembed using an RM5200 board.
387     These "modded" CPU modules for O2 systems are not supported/tested, although,
388     in theory, they should be functional, but may suffer from the same problems
389     listed above.
390     </impo>
391    
392     <impo>
393     <b><c>(7)</c></b> Octane support in Linux shoul be regarded as
394     <e><c>experimental</c></e>. Support for this particular machine from SGI has
395     been progressing quite well, and the Linux kernel functions reasonably well.
396     The current status for this system may be found here:
397     <uri>http://helios.et.put.poznan.pl/~sskowron/ip30/</uri>. Wider
398     support in Gentoo for this system will be available in the future, so watch
399     this space closely for more details.

403     <b><c>(8)</c></b> The maximum amount of RAM supported in the Indy, Challenge S,
404     Indigo2 (not Power or Impact), and O2 systems is 256MB, due to no HIGHMEM
405     support the Linux kernel. Only a 64-bit kernel w/ HIGHMEM support can properly
406     detect RAM amounts greater than 256MB on these systems. However, do note that
407     using HIGHMEM does incur a performance hit, so it should only be used when
408     necessary.

472     Cobalt support is still in testing phases, and the documentation is incomplete
473     and has not yet been fully integrated into this guide, nor into the Gentoo
474     Handbook. Gentoo does run on these systems, and installation stages may be
475     found in the <c>experimental/mips</c> folder on your nearest mirror. Expect
476     many neat things for Cobalt machines in the coming months.

479 swift 1.1 <note>
480 swift 1.4 2.6 has been tested to boot on the Cobalt RaQ2 and Qube2 systems, however
481     booting this kernel requires the use of a new bootloader (called <c>colo</c>)
482     that can either replace the original Cobalt bootloader in the system's flash
483     chip, or the new boot loader can be <e>chain loaded</e>, or booted by the old
484     bootloader. Those interested in learning more about this new bootloader may
485     visit the webpage of its author, who also maintains several 2.4/2.6 patchsets
486     for these machines. The webpage can be found here:
487     <uri>http://www.colonel-panic.org/cobalt-mips/</uri>. This new bootloader is
488     available in the portage tree as <c>sys-boot/colo</c>.

500     The Playstation 2 is a specialized MIPS system, using an R5900 MIPS processor
501     (EmotionEngine) manufactured by Toshiba. The support for this processor is
502     extremely limited, and only found in the development toolchains available in
503     the PS2 Linux Kit and via some patches available on the PS2 Linux Homepage.
504     There was a limited amount of work done on porting Gentoo to the PS2 Linux
505     Kit, however it is incomplete as of this writing. Those interested may visit
506     <uri>http://playstation2-linux.com/projects/gentoo-ps2/</uri> if they are
507     interested in assisting or completing the port. Additional information on
508     PS2 Compiler Toolchains can be found at <uri>http://www.ps2dev.org/</uri>.

512     Gentoo/MIPS has also been installed on a SiByte BCM1250 Machine, a Big-endian,
513     dual-processor MIPS machine. Currently, only one person to date has done this,
514     but more people willing to test Gentoo on such hardware are welcomed to try
515     and report results.

527     <li>
528 swift 1.4 128MB RAM - More ram is better, as Gentoo currently uses the gcc-3.2.x and
529     greater versions of gcc. These versions of gcc tend to consume more memory
530     than their older 2.95.x counterparts, and on the merging of large packages,
531     anything less than 128MB of ram could make gcc fail to compile the package,
532     or mysteriously stop in the middle of compiliation. A recommended amount
533     of ram is 160MB.
534 swift 1.1 </li>
535     <li>
536 swift 1.4 9GB Hard Drive Space - 9GB is more or less the recommended minimum. It is
537     enough space to install Gentoo on and leaves extra space for daily
538     activities on the machine. Gentoo has been installed on smaller drives,
539     the smallest being a 3.2GB drive, but it does not leave alot of room for
540     much else.
