Also check out Dina, it will allow a network install by hosting the VM on a PC or Mac. Although you'll need something that can mount IRIX CDs and read the EFS file system on them. When I set up Dina myself, I used my Indigo2 to read the disks, so I don't have experience of reading them on a PC or Mac.

Root passwords can be removed, but you need either a second SGI, or a second disk with IRIX on it. I'd advise not wiping the HDD if you can in case it has some nice software on it. Better to get a replacement disk, get IRIX onto it somehow, then remove the root password from your current HDD.

The lack of a display could be due to either a res/refresh rate your monitor doesn't support, or IRIX is running in headless mode. You'll need single user access to fix though...
