SGI Indigo, WTB Power supply? Burning smell?

Found the fried component! A surface mount yellow rectangular capacitor mounted on the bottom of the CPU board, somewhat near the audio DAC section. I wonder if all the similar caps that are on the bottom should be replaced. Maybe one went bad, but if one went then the others might be at risk as well. After removing the PSU to open it up, I found that it's the R4K model power supply (Yay!) and there doesn't seem to be anything fried in it. One odd thing, and I can't remember my SGI enough. I get the TOD clock error on the Indigo, and I get no startup chime tune sound. It had kind of a sputtering tick from the speaker (perhaps the fried cap is in the audio section.) Anyone know if the chime should play before the time of day clock error? -- Ethan O'Toole
