Adding a soundcard and GFX-1600SW to my Silicon Graphics Fuel

The Fuel is Silicon Graphics’ last MIPS based entry level graphics workstation. Like it’s bigger brother the Tezro, it’s based around the updated innards of the Origin 3000 machines – in the same way the Octane used the same innards as the Origin 2000.

The family lineage goes like this:

Origin 3000 -> Origin 300 -> Tezro -> Fuel
Origin 2000 -> Origin 200 -> Octane

The advantage this gives the Fuel is much faster memory bus speeds, as well as multiple PCI channels and faster throughput to the graphics card. Unless you need multi-CPUs, you’ll find Fuel faster than Octane. Taking into account the cost of an Octane2 with a V10 board set, the Fuel represents a massive bargain right now.

SGI sold the Fuel with no sound card, providing extra cost options of either a PCI based card, or a USB sound system. This does actually make sense, if you think about Fuel’s target CAD and graphics markets – cut the cost of manufacturing by pulling out parts that aren’t used by the majority of the client base.

My current problem was two-fold:

  1. I want to get one of my 1600SW screens wired into my Fuel
  2. I want some sound on the Fuel as well

Solution to problem number one is to buy a Niktec GFX-1600SW. It takes up a single PCI slot for power (so no drivers needed) and converts DVI to OpenLDI. It’s a nice neat internal solution that’ll work on anything with a spare PCI slot.

Solution to problem number 2 is to purchase a Soundblaster Audigy 2 ZS. This is supported natively under IRIX, and is much much cheaper than the other supported sound options for SGI gear.

Total time to plug everything in was under 5 minutes – the Fuel is very very easy to get into.

The only issue I faced was that I’d forgotten to reconfigure the X server before shutting down the machine. The configured resolution was 1900×1280, for the 24″ CRT I had plugged in before. This would clearly not work with the 1600SW.

The easiest option to this was to hit ESC once the Fuel had started booting, to drop into the graphical PROM menu. The default graphics settings appear to be 1024×768, and these can’t be changed, so no matter what you have plugged into a Silicon Graphics machine, you should always have something displayed during power on.

From the main PROM menu I entered the PROM monitor, then typed single and hit enter. This tells the machine to boot IRIX, but drop into single user mode. You just then need to enter the root password when prompted, and you have a root login in single user mode.

Reconfiguring the X server was then as straightforward as entering:

/usr/gfx/setmon 1600x1024_60

Answer No to whether or not you want this as the power on default. Remember, you can’t change that, and trying to will cause setmon to error out. Once setmon has done it’s magic, just type reboot, and wait for the machine to restart.

The graphical login window should pop up and you’ll be able to login to X with the new resolution fitting nicely on your 1600SW.

We can check the graphics board set configuration from the command line using the gfxinfo command:

valaraukar # /usr/gfx/gfxinfo 
Graphics board 0 is "ODYSSEY" graphics.
        Managed (":0.0") 1600x1024 
        BUZZ version B.1
        PB&J version 1
        32MB memory
                Banks: 2, CAS latency: 3
         Monitor 0 type: UFC 0
        Channel 0:
         Origin = (0,0)
         Video Output: 1600 pixels, 1024 lines, 60.00Hz (1600x1024_60)

Here’s the output from hinv after the hacking about:

You can see the Soundblaster Audigy 2 ZS card is recognised by the Iris Audio Processor driver – no messing around needed.

Again, none of this required any fiddling with drivers or messing around – you should be able to cheaply add sound to your Fuel in 10 minutes or less, and I picked up the Soundblaster Audigy 2 ZS card for £19.

    So how good is a Fuel with a sound card for playing Quake2 or something similar?
    I’ve recently bought a Fuel (NZ$200 or about 70GBP) so I’m quite interested in adding a sound card.

    Quake2 isn’t a fantastic benchmark – for that sort of money you’ll get a PC that’ll be much faster at playing games.
    However Q2 and Q3 are very playable and usable on Fuel – have a look at Ian’s site at http://www.futuretech.blinkenlights.nl/quake2bench.html for some numbers.

    Cheers!
