You use a hard disk as a working area, setting the disklabel with fx and with a single EFS partition. After it is fully prepared, you can either use dd to copy it to an image file, or burn the disk device directly using cdrecord.
Take a look here:

Rather than creating a bootable DVD from scratch, the idea is that you dd the first IRIX boot CD to a hard disk. You then use fx to expand that EFS filesystem to match a DVD. From that point it's just a matter of copying the files you want into it and then burning an image of the hard disk to a DVD.
Incidentally I came across that page originally because I'd found some cheap HP C7499 SCSI DVD drives on ebay and wondered if they'd work on SGI. Turns out they're rebadged Pioneers and work very well indeed once you update the firmware to the latest available on the Pioneer site (I had some oddities before that). They seem to be very cheap for some reason - mine was ~£20 - much cheaper than the equivalent (and rare) Pioneer.
