I started up my indigo today, it has the same time of day error. The
chime does play before the message is displayed.

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?
