`Introduction

`
`Indigo 2 fiont with Indigo 2 Video breakout box.
`
`The Indigo 2 (codename "Fullhouse") was obviously successor to the Indigo series and as a highend desktop workstation
`
`it was placed in the market above the low end Indy, which was actually released a while later (until the release of it the
`
`original In_clig(_) was the low end). Judging by outer appearance only there have been two versions of this rmchine: one in a
`
`teal case and another in a purple case. Going deeper on hardware level there are even more versions. 3 completely
`
`dilferent implementations of the MIPS architectures have been available: R4x00 and R1 0000 based Indigo 2 systems and
`
`the rare R8000 based ones called POWER Indigo 2. Speaking of graphics there have been two dijferent types:
`
`Newport/Express and Impact graphics.
`
`Indigo 2 Impact R10000 fiont.
`
`Confiising? Yes, it is at first, but this page will try to show the available options. Keep in mind how the Indigo 2 series
`
`evolved: At first there were the R4x00 based systems with Newport/Express graphics (details follow), which were shipped
`
`with teal skins. The last generation of the Indigo 2 systems were R10000 models with Impact graphics, that came with
`
`purple skins. Before the relase of the R10000 CPU there have been teal Impact systems with R4x00 CPU and the
`
`POWER Indigo 2 computers with R8000 CPU. With the introduction of Impact graphics on R4x00 systems the skins
`
`turned purple. Judging the system by the color of skins or labels can only give a first indication ofwhat type of machine it
`
`actually is.

`
`Graphics
`
`Overview
`
`All graphics options attach to the proprietary GIO64 bus that is accessible via a special riser card that is integrated in all
`
`Indigo 2 systems (see below).
`
`0 Challenge M server
`
`The Challenge M is basically a R4K or R8K Indigo 2 without a graphics option installed.

`
`Impact Graphics
`
`Supported on: R4x00 and R10000 models. Impact is not supported on Power Indigo 2 systems with R8000! While
`
`Silicon Graphics had planned to support this configuration they did not release a driver for this. (This information has
`
`been obsoleted by history itself There are reports of working R8000 Impact systems so there must be support in
`
`IRIX.)
`
`The requirements on IP22 systems for Impact Graphics are as follows (Impact is not useable on IP26 and should work in
`
`all unmodified R1 0000 models):

`
`Dual Head Impact systems with more than just two SI cards need to have a newer Impact powersupply (060-0021-001)
`installed.
`
`Other
`
`Drives / SCSI Devices
`
`All Indigo 2 systems have two narrow SCSI Channels. One is used for internal drives, the other for external devices.
`
`Because of the number of internal drivebays the internal SCSI channel is limited to 3 devices. Both channels are Fast SCSI

`
`Expansion Slots
`
`On all Indigo 2 systems the expansion slots are located on a rnidplane / riser card that plugs ir1to the main system board.
`
`The Indigo 2 chassis allows physical access to 4 slots ir1 which option cards may be installed. The graphs ir1 this section
`
`show the stacked layout ofthe EISA and GIO 64 expansion slots on the two distinct (Express and Impact Variant) riser
`
`card types used ir1 Indigo 2 machines.
`
`The Express / Extreme riser card that has 4 EISA slots and 3 GIO64 slots. The upper two GIO slots in the system are
`
`1ogical/ electrical the same thus limiting the number of GIO options that may be installed to 2.

`[========== GIO #0 Slot #1 ========== 1
`
`Impact systems have a dilferent layout ofthe riser card. There are only 3 EISA slots left but now there are 4 GIO64 slots
`
`plus 3.3V connectors which are required to meet the power requirements of Impact graphics. Similar to the Express riser
`
`card the GIO64 slots come in pairs that are logically and electrically the same. Again the number of installable GIO64

`
`The reason for the at first glance strange GIO64 arrangement is that some of the installable options are multi-card designs
`
`that co11ld block available slots. The additional slots in the existing design leave better possibilities to arrange the installed
`
`options in the 4 available physical slots.
`
`Also worthy to note: Not all cards that have a G10 64 connector to plug into one of the slots really attach to the bus.
`
`Examples for these behaviour are video options that draw power fiom the GIO64 connector but do not connect to the bus
`
`itselfbecause they actually attach to the graphics subsystem via additional cables and connectors.

`

`
`Specials
`
`Challenge M
`
`The Challenge M is the server model of the Indigo 2 line. It was introduced early on featuring a R4K CPU and was also
`
`sold as Power Challenge M featuring the R8K processor. The Challenge M was dropped later on in the product life cycle,
`
`possibly ir1 fivour of the larger Challenge DM server.
`
`The system is not very much diiferent from the workstation Indigo 2. The Challenge M lacks the graphics option but is
`
`otherwise the same machine as the Indigo 2. A conversion into an Indigo 2 is thus trivial
`
`Challenge M Vault
`
`Another use ofthe Indigo 2 chassis design is the Challenge M Vvault. It is an external SCSI enclosure that uses the same
`
`design as the Indigo 2. On the fiont the only obvious difference is the label The back is quite diiferent though, beside the

`
`PSU there are only two SCSI connectors.
`
`Internally the Vault is similar to the Indigo 2. The space where the rnairiboard and GIO riser would be, the chassis is erripty
`
`or used for cabling. The norrml spaces for one 5.25" drive and two 3.5" drives on the middle/right side ofthe Vault are
`
`present. In the GIO card cage there is additional space to mount four 3.5" drives.
`
`An Indigo 2 or Challenge M expanded with a vault can use eight 3.5" drives (four accessible) and two 5.25“ drives (two
`
`accessible). More SCSI devices are possible when additional SCSI controllers are installed.

`Special Applications
`
`For special applications special versions of the Indigo 2 were built either by SGI or other companies - rackrriount systems
`
`for medical equipment for example.
`
`Problems
`
`Operating System
`
`Choosing an operating system
`
`The first Indigo 2 systerris were introduced during the 4Dl-4.x era. These were based on the R4000 microprocessor and
`
`featured Express graphics (Elan, X3. Support for new hardware was added in future releases during this period and later
`on in the 4Dl-5.x era.
`
`Major milestones include the introduction ofthe Irripact graphics options as well as the step fiom the R4000 to the
`
`Rl0000 CPU. For Impact graphics special versions of the IRIX 5.3 and IRIX 6.2 release were oifered. Similarly a
`
`special release of IRIX 6.2 was rriade for the R10000 CPU upgrade.
`
`General support for all Indigo 2 variants can be found in the all platform IRIX 6.5. The support for the remaining legacy
`
`systems like the Indigo 2 was dropped after 6.5.22 making IRIX 6.5.22 the last version to support any ofthese systems.

`
`NVRAM Password
`
`What to do if you don't know the NVRAM password.
`
`Indigo 2 systems do have a jumper that allows access to the advanced PROM options without entering a password. The
`
`description of the procedure is also in the Indigo 2 Owners Guide and the Indigo 2 IMPACT Owners Guide
`
`(Troubleshooting section):
`
`1. Power down system and remove power cord.
`
`2. Remove cover of the system
`
`3. Remove the jumper which is located on the CPU board underneath the 5.25" slot (near the firont edge of the main
`
`logic board).
`
`Install power cord and power up the system
`
`Enter System Maintenance menue and issue the resetpw command.
`
`Power ofl" the system
`
`Put the jumper back onto it's previous position.
`
`Put the cover back on. The machine should have no NVRAM password by now.

`
`Powersupply
`
`Powersupply problems. Sudden shutdowns and such.
`
`People on the newsgroups have reported ofvarious problems with the powersupplies on Indigo 2s. Not all systems are
`
`alfected, it seems most common with Impact or Impact ready machines (both R4x00 and R1 0000).
`
`Typical problems are machines that shut olf during their work or that don't come up properly. Some people reported that
`
`the fans on their machines start spinning and that the LEDs go on but little else happens after the power button is pressed.
`
`There is no real fix, but unplugging the system for a while (as in 15-30 minutes) often helps for the moment. This might be
`
`caused by a number of things: (a) Problems outside the system, (b) a slowly dying powersupply or (c) some random
`
`flakieness ofthe soft power- on circuit.
`
`Cleaning out the dust inside the machine might also be a good idea. Heat can affect both the computer itselfas well as its
`
`powersupply.

`
`It is not officially supported, but it is possible to have 1 GB RAM in an R10000 Indigo 2, but none of the other Indigo 2
