This image worked. The other did not. I opened it up on my pc with hfv explorer. Then I coppied it to a flash on my mac mini. Then I opened it on my old ibook g3 900 and it worked. But it gave error message as you said it needs to be the boot volume. But those old systems dont run on SE only 128k. So I copied it to a 1.44 floppy with the system from my ontrack disk. Booted up and showed the old flight sim icon. But when I started the app it said please insert the master disk. I dont have a master disk.
