SGI Indy front. The Indy (codename 'Guinness') was the low-end successor to the Indigo product line introduced shortly after the more versatile 2 line was available. The Indy is the only SGI workstation that follows the 'pizza box' chassis design that was so popular with the Sun workstations of this era (Sparcstation 4, 5, 10, 20, etc.). Given the small footprint the Indy had reasonable computing power and a surprising amount of nice features (audio, video input, ISDN) especially considering the time it was introduced.

The Indy was always accompanied by a small digital video camera intended for video conferencing, similar to the webcams we have become used to. Regarding technology of the base system it is more like a straight development from the Indigo line rather than a radical new invention. The newest features compared to the Indigo are the builtin ISDN port and a Video Input that together with a camera (IndyCam) could also be used for video conferencing solutions. [] History 1993, July Indy with 100 MHz R4000PC and R4000SC processors and 24bit graphics announced to ship in 3rd quarter. Indy R4000PC/100 with Newport graphics, 16MB, no HD, 15', accessories and IRIX: $4,995 1994, January R4400 with 150 MHz available for Indy series in March. R5000PC 150MHz CPU. The Indy main logic board is the IP24 CPU board (reported as IP22 by hinv) which integrates all basic components of the system including memory, I/O subsystem or GIO expansions.

The CPUs are added using modules which connect to the IP24 using a special socket. The modules include aside from the CPU itself also the second level cache (if there is any). The layout and the connector of the Indy CPU modules is completely different from the modules used on Indigo and Indigo 2 so it is not possible to swap CPUs between these models. [] Memory Overview Type: 36bit wide 72pin SIMMs (fast page mode, parity, 70 or 60ns) Sockets: 8 (2 * 4 sockets) Minimum configuration: 32 MB (8 * 4 MB SIMMs) Maximum configuration: 256 MB (8 * 32 MB SIMMs) Memory modules have to be added in groups of 4 according to the following schematic. It is possible to have different types of modules in the 2 banks but within one bank all 4 modules must be of the same type. The Indy is known to support 4, 16 and 32 MB memory modules. ##S8################ ##S7################ Bank ##S6################ 1 ##S5################ / ##S4################ ##S3################ Bank ##S2################ 0 ##S1################ / ->front ___________________________________________.

XL8 graphics board. The graphics options plug into the main logic board (IP24) and attach to the system using the GIO32bis bus. • Graphics (XL/XGE) • Graphics (XZ) Newport graphics was renamed to XGE when the R5000 CPU introduced to differentiate R5000/Newport (XGE) from R4x00/Newport (XL) setups. Because of the floating point characteristics of the new R5000 Newport graphics on these machines performed in many cases better than Express setups so the aim was not to use the XL name any longer for Newport style options because that had a 'inferior to XZ' ring to it. With Newport graphics a dual head setup is possible, but it requires a specific second XL card because of the differences in GIO slot layout between the mainboard and the normal XL graphics adapter. The XZ graphics option for Indy was introduced after the Indy release, so not all PROM versions recognize it.

The following table indicates the required PROM version. Graphics Upgrade Requires PROM date (see 'version' in PROM) XZ June 20, 1994 or later The Challenge S is not equipped with a graphics board. [] Other Drives / SCSI Devices The Indy has a single SCSI channel (narrow SCSI) that allows internal and external SCSI devices to be used.

The total number of devices allowed on the SCSI chain is 7. See Chassis for details on the internal drivebays. The SCSI chipset used is a Western Digital 33C93B Fast SCSI controller. The Challenge-S has a single onboard narrow SCSI controller that allows 7 internal and external SCSI devices to be used (Western Digital 33C93B).

See Chassis for details on the internal drivebays. In addition to that all Challenge S systems come with an IOPLUS board that adds 2 differential (HVD) SCSI controllers (Western Digital 33C95A), that support up to 15 devices each. All ports on the IOPLUS board (2 differential SCSI, secondary ethernet) are only available from within IRIX. So the root drive must be installed to the onboard narrow SCSI controller that the Challenge S and Indy have in common. As an option a 21MB floptical disk drive made by Insite was available for both the Indy and the Challenge S. This drive was also able to write standard 3.5' diskettes.

Connectors (Indy workstation) • Multimedia: • 5 stereo 1/8' phone jacks, for headphone, microphone, speakers, etc. • 1 composite video input • SVideo 4 pin Mini-DIN • 60 pin Indycam connector • Networking: • 15 pin AUI network connector • RJ45 ISDN connector • RJ45 10BaseT network connector • Both network connectors (AUI and 10BaseT) connect to the same ethernet port, so only one can be used. Phobos G130 Fast Ethernet The Indy has two GIO32bis expansion slots on the CPU board that can be used for additional hardware (see options). The space for GIO-bus expansion cards on Indy systems is usually taken by the graphics board, which passes the connection through so that two GIO32 cards can be installed. The Challenge S has two GIO32bis expansion slots on the CPU board that can be used for additional hardware (see options). Note that the IOPLUS board uses one DMA line which means that only one of the two GIO slots supports DMA and the other not. GIO slot #0 is DMA capable and should support all GIO expansion cards, GIO slot #1 is not DMA capable and thus some expansion cards won't work in this slot.

All Indy systems come in a slim blue 'granite-look' chassis which is similar in size to the pizza box designs common in that workstation era (Sun Sparcstations come to mind).

The Challenge S chassis is the same as the one used for Indy systems but the plastic skins have a noticeable hint of green in their color and lack the granite look the Indy has. They have all logos including the cube silkscreened on them. The cube logo is not a shiny badge as it is on Indy systems. Both have the following dimensions: width: 40.6 cm / 16' height: 7.6 cm / 3' depth: 35.6 cm / 14' weight: 7.2 kg / 16 lbs. SGI Indy interior with R4600 CPU and XZ graphics. The chassis has space for two internal 3.5' SCSI devices (each up to 1' high).

The upper drive can be accessed from the outside if one of the original floptical drives made by Insite is used. Other SCSI floppies or flopticals drives most likely will not fit physically into the correct position on the Indy. It is possible to install a second harddrive but because of the passive cooling of the Indy the amount of heat generated by the drive has to be considered.

The only fan to provide airflow is located in the powersupply. Aside from the usual logo and the shiny 'R5000' badge on R5000 systems there are no other markings / color codes for CPU or graphics variants. It seems the position of the cube logo was different between R4K (before 'Indy') and R5K (before 'Silicon Graphics') models.

Indy with Control Data labels. Relabeld Indy /Challenge S systems were available from several companies, the most common being: • Control Data: Original skins with 'Control Data 9000' logo on a sticker. • Reynolds + Reynolds: Original skins with black badges.

Model ERA Advantge S. • Siemens Nixdorf: Original skins with different label. • Tandem: Black skins with tandem logo. Special Configurations Cyclone Indy: Raster Image Processor from Colorbus Corp. The system was a stock Indy but had one GIO slot occupied by the interface card for a color copier or printer.

The WebFORCE Indy was sold by Silicon Graphics with the following software package: • WebFORCE Authoring • WebSPACE Authoring • Netscape Browser • Netsite Server • MPEG Encoder • Adobe Photoshop • Adobe Illustrator • Digital Media Tools • SoftWindows Indy Laptop There is no such thing as an Indy laptop from SGI. The machines in Twister are fake systems built for the movie. However there was one made by a third party for military applications or use in heavy industry (mining, oil & gas).

The company website is available at www.rsi-cri.com and they still produce ruggedized versions of workstations, servers and supercomputers (among them special rackmount versions of O2, Octane or Origin). Most of the systems they build can hardly be called 'laptop' though. Developer Versions There were probably various special Indy versions which were used in software development. A known version is the Indy with Ultra 64 Development Board which was used for developing games for the Nintendo N64 system. The Indy is a stock system from SGI but comes with a fullsize GIO32 option board, that contains a full N64 with it's own graphics hardware and processor (VR4300). Scientific Atlanta There was a special version of the Indy which was hidden in a larger black case that was used for cable / video on demand tests.

According to Greg Douglas (Message ID: ) the system 'has proprietary boot PROM, won't run Irix, no hard drive, and a slightly modified (different connectors) motherboard' and seems to have a modified XL24 graphics board. Indy Case The is a briefcase which has the blue Indy cover on its top side. Below 'Indy' the word 'Case' is silkscreened on the front of that cover. [] Problems Operating System Choosing an operating system. The first IRIX version to support the Indy was the system specific release. As time went by newer IRIX releases featured support for newer hardware like upgrade processors and optional hardware (e.g.

The Presenter). System specific IRIX releases were produced for the introduction of new hardware. While most support is present in full Indy support can be found only in the later all platform releases and. The support for the remaining legacy systems like the Indy was dropped after 6.5.22 making the last version to support any of these systems. Choosing an appropriate IRIX release for the Indy is dependant on the CPU and the amount of memory installed: 128 MB R4400 CPU R4600 CPU R5000 CPU Powersupply System does not power up or shows miscellaneous faults.

Verbose problem description: The system does not power up when the power button is pressed. A failing powersupply can cause a number of different faults. In Indy systems two different models of powersupplies were used.

The older models did come with a powersupply manufactured by Nidec, the newer models come with one manufactured by Sony. The Nidec powersupply is known to be failure-prone, no such thing can be said about the Sony model. If the powersupply is dead the system obviously won't power up. If it just starts failing the failures may not appear to be related to the powersupply.

Indy systems that show odd behaviour may be getting into powersupply trouble. It is recommended to swap with a known good one to make sure. Crash System suddenly freezes and won't come up again. Verbose problem description: The system hangs without warning and cannot be shutdown with the power switch and after a power cycle it shows a red LED. In this case unplug the power cord and check if all SIMMs are properly seated. To make sure try booting with only one set of SIMMs (4 modules) installed or try even different ones. Indycam How to use the Indycam without graphical tools.

Basically this is easy. Vidtomem by default saves a single frame from the video input into a file. To save a picture from the Indycam to /tmp/cap-00000.rgb (the counter is automatically appended) the following command can be used: vidtomem -f /tmp/cap -v 0 To convert this image imgcopy is a handy tool. To convert it into JFIF the following command is everything required: imgcopy cap-00000.rgb cap-00000.jpg Recommended reading are the manpages of imgcopy, vidtomem and vino. I've put a simple example. NVRAM Password What to do if you don't know the NVRAM password.

Burst The Gravity Download Free there. • Power down system and remove power cord. • Remove cover of the system. • Remove the jumper between CPU module and RAM (it's right next to the power connectors). • Install power cord and power up the system. • Enter System Maintenance menue and issue the resetpw command. • Power off 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. NVRAM corrupt How to fix a bad ethernet address (eaddr). The Dallas watchdog timer that stores the machines ethernet address depends on the battery which is included on the chip. As most Indy systems are over 10 years old these batteries have come past the end of their expected lifespan. If the battery fails, the Indy will begin to forget PROM settings including the ethernet address.

Typically an Indy with a broken ethernet address will still boot, but IRIX will complain and not start up networking. With the exception from the ethernet address all other NVRAM settings can be fixed by using resetenv in the Command Monitor. Inside the Command Monitor a new setting for the eaddr variable can be set manually. The machine will forget it once it is powered off. The eaddr needs to be set to the builtin Ethernet adapters MAC address. All SGI MAC addresses start with 08:00:69 and continue with the serial number of the machine.

On a local network any valid MAC address will do. Replace the xx in the following example with the serial number: setenv -f eaddr 08:00:69:xx:xx:xx describes how to replace the Dallas chip and how to set the correct ethernet address. The real ethernet address of your Indy can is printed on the small barcode sticker at the back of the machine. Open Indy How to open an SGI Indy. In theory it is easy to open an Indy system but sometimes the whole mechanism gets stuck a bit so it probably makes sense to give some explanations in addition to the information given in the Indy Owners Guide (see Further Information). The following is a short description of the typical procedure: Place system on a desk before you so that the front is facing you.

Looking from the top you should see a black and a blue nose at the back of the system. Place the thumb of your right hand on the black one and pull the blue one (which is actually part of the cover) up. When lifted about 1mm it should be possible to pull the cover to the front. After approximately 1/2 an inch it is possible to lift the cover up. If the cover is stuck it doesn't hurt to use the left hand to pull at the front of the cover. At the bottom of the machine there is some space that should allow you to pull while lifting the back of the cover with the right hand. In no case it makes sense to fiddle with the lockbar that sticks out below the black nose at the back.

It is glued to the cover of the Indy and does not have a function except that a lock can be added to secure the cover.
