I have an Indy with a 133MHz R4600. I recently upgraded it--or attempted to--to 256MB of RAM, from the 32 it came to me with. The RAM is all recognized by the system--at least,
hinv in the PROM monitor reports 256MB--but when I try to start an IRIX installation, after it boots into the miniroot and mounts the target partition, it dies with:
Code:
PANIC: IRIX Killed due to internal Error
at PC:0x881032f4 ep:0x887f1ce8
[Press reset to restart the machine.]
On the off chance that it was a cosmic ray flipping a bit or something, I tried a couple more times, but the same thing happened (although unfortunately, I did not take note of whether the PC and ep values were the same each time). I did also try with half the RAM removed (the RAM in bank 1, since it's easier to remove), and it at least progressed to the "Inst>" prompt, but I'm under the impression that the more RAM, the better, where later versions of IRIX are concerned, so I didn't proceed. Instead, I ran IDE from the 6.5.22 overlay 1 disc, and after a while, it started producing screenfuls of identical ECC exceptions, culminating in "ERROR: Failure detected on the CPU base board.":
It took some time to get to this point, although I don't know how much, if it's even relevant (I left the room to go do something else once I saw that it was going to take a while to get any output other than the "SGI Version 6.5 IP22 IDE field" banner, hardware inventory, and spinner).
Is this error accurate, or could faulty memory cause IDE to detect a CPU failure? Also, when I first installed the RAM,
hinv only reported 128MB, so I removed and reinstalled the RAM in bank 1 and then all 256MB were detected (I'd forgotten how fiddly those old SIMM slots could be)--could this potentially have shorted and fried something?
