Starting with Octane, the diagnostics are in the prom itself.
Every system has a set of power-on diagnostics in the PROM firmware. Things like a basic test of the CPU, L1 and L2 cache, RAM, and the first serial port.
The diagnostics (option [3] from the PROM menu) is a standalone program. A standalone program doesn't need the IRIX kernel but operates on bare metal. For older versions of IRIX this is a standalone program embedded in the vh (volume header), for newer IRIX, and all 64bit systems, sash (in the vh) executes '/stand/ide' from the system disk. These diagnostics are installed by IRIX. For some systems they exercise just about any part of the system, but for newer systems the graphics tests (VPRo, IR, other big iron graphics) are not included.
Then there are the online diagnostics (stress test for the system) and the graphics tests for systems where they are not part of the standalone diagnostics. These are part of Field Engineer's Diagnostics discs, and you didn't get those with the system. Instead, you were expected to get a support contract with your big iron, and if it behaved erratically you called support and they'd fix it. Ironically, the IR diagnostics
are part of IRIX and the VPro diagnostics are not which is a strange twist of events.
NB: it looks like the system of the O.P. has a wiped, corrupt or missing system disk. The result: PROM cannot load IRIX or standalone diagnostics. If you attach a CD-ROM drive with an IRIX OS installation disc, the PROM will look for diagnostics there as well, and load those if it can't load diagnostics from the system disc.
