How do I open SGI ISOs on Windows? - DevilMaster - 04-06-2020
I have found an ISO containing several graphical demos meant to be run on an Onyx. Normally, I'd take it to a friend of mine who has an Onyx, but these day I can't due to the quarantine. So I thought that, even though I can't run the programs, I'd still like to know what it contains. And here's the bad surprise: neither WinRAR nor WinCDEmu can open it, which means it's not a standard ISO file. What software can I use to open it?

These aren't ISO images. They're EFS images that are mislabeled because people don't know any better.
Windows cannot understand EFS. If you have WSL you can try EFS2TAR, but otherwise you're gonna need a Linux or BSD based system to extract the contents

This blog has a great run-down of the EFS problem and development of the EFS2TAR utility.

It would be great to get the CD archived. I don't recall seeing an Onyx-specific demo in the random repositories I've run across.

Windows System for Linux. A shitty "Linux addon" in Windows 10 and up.

Basically you slap it in Linux use efs2tar and then it’s a tar and you can open it

You can't. You can use it in WSL, but overall if you can't figure that out you're better off using an Ubuntu live CD or something and using efs2tar off there.
Or if you are doing a network install, use a network install guide. I have them for a few OSes. Net BSD and illumos are the easiest.

I would download virtual box and set up a vm of unbuntu real quick and do it that way. There’s a bunch of stuff to get it setup the readme doesn’t describe it well but it does work very well.
on a Linux machine git clone from the terminal the repository https://github.com/sophaskins/efs2tar
