I have a Challenge S that I previously had running IRIX and OpenBSD at one point with no issues, and recently hauled it out to tinker with.

Something has to have gone wrong with the hardware, or I'm just out of practice. I've been trying to install IRIX, old OpenBSD, or NetBSD with no luck. I've tried everything I can think of:

* Real HDD, BlueSCSI, SCSI2SD
* Installing via Reanimator over the network
* Installing via CD
* New SCSI cables, new terminators
* Swapping RAM

IRIX 6.5.22 tries to start, but gives me a "vector=UTLB Miss." I thought RAM, but unless every one I have has gone bad, I'm not sure. I have plenty of SIMMs and have tried a bunch of configurations with the same result. I returned it to the same config that I knew worked, real HDD (though not the same actual drive as when it worked (I used it for another project), though I have tried several drives), same terminator configuration.

NetBSD from CD starts, but ends up repeating a SCSI timeout over and over. OpenBSD from CD hangs after complaining about the clock being wrong.

Any ideas what I might check? I know these can have power supply issues that manifest as weird issues. Or maybe the RTC battery?

Here's an hinv with the CDROM connected:

>> hinv
                  System: IP22

              SCSI CDROM: scsi(0)cdrom(6)

Here's the UTLB Miss error when trying to install via Reanimator:
