An SGI Fuel
Another SGI Fuel

General information

The Silicon Graphics Fuel, introduced in 2002, was intended to be a single-CPU midrange solution for those customers who did not need multiple-CPU capability, thus offering a much cheaper system compared to a baseline Tezro or top-spec single-CPU Octane2.

Contrary to popular belief, Fuel was not a successor to O2. SGI never made a follow-on to O2; a new system was designed (internally known as the Banana2000 or b2k) but was never evolved beyond a prototype.

System architecture

Fuel shares the IP35-architecture with Origin 300, Origin 3000, Onyx 3000 and Tezro systems.

CPU options

Memory subsystem

512 MBytes to 4 Gbytes total system memory using up to four DDR SDRAM DIMMs

On introduction SGI claimed an industry-leading 3.2 GByte-per-second processor to memory bandwidth, and half that to the graphics subsystem. The Double Data Rate (DDR) DIMMS used are compatible with those used in the Origin 3000, Origin 300, and Origin 350. There are a total of four slots, organized into two banks of two slots. Each bank must contain parts of the same size, but each bank can vary in size.

I/O subsystem

  • PS2 Mouse/Keyboard ports
  • One 10BaseT/100BaseT Ethernet
  • Two serial RS232 ports (DB9)
  • One bidirectional parallel port
  • Two USB ports
  • 4 PCI slots: 2x 66MHz and 2x 33MHz 64bit
  • 2 Internal SCSI Controllers QL12160

Graphics subsystem

The VPro graphics chipset that SGI started for the Octane2 was also used for this system.

  • VPro10 32 MegaBytes RAM
  • VPro12 128 MegaBytes RAM
  • for V12: Dual Channel Display option (2 DVI-I ports)


Fuel comes with no sound option installed, however the system can be expanded with PCI or USB soundcards (see "Add-on options")

Add-on options

First section will cover PCI/PCI-X cards, with the official SGI Digital Media options listed first, then alphabetical by interface/function. Second section will cover devices interfaced through said cards that are known to work.

IRIX support

IRIX Versions from 6.5.17 up to the latest overlay (6.5.30 at this time) are supported on this machine. Firewire support became functional around 6.5.27

IRIX and hardware bugs

xfs_fsr locks up the system while running against the file system on any firewire drive. This has been a problem for over two years now with no repair in sight.

Temperature sensing on early Fuel mainboards is notoriously prone to failure, rendering the computer inoperable if environment monitoring is left on. Amateur repairs are possible, see here : [1]

Fuel PSU Issue and Environmental monitoring

Fuel power supplies are variants of off-the-shelf units offered for consumer PCs. However the pinouts, if not hte voltages and functions, differ even though the OEM part numbers do not. This is described in this forum thread and includes speculation about substituting one for the other. If you pursue this please be aware that you do so at your own risk, but please share the results with the community if you are successful.

TODO: write about L1 monitoring of PSU fan speeds and the Fuel just knowing its not a SGI PSU.
