The last thing it said it was testing was the memory.

As I said earlier, I am not able to boot with command-option to get a boot 
menu.  It never gets to the boot menu, so I can't ever choose a different drive 
to boot from.

As I am writing, I just looked at the test screen and I see that it now says 50 
minutes.  It was stuck on 10 minutes for more than 30 or 40 minutes, but it 
finally updated the time, though the progress bar is still only at about 30% 
(and it's been over an hour, I think).

Maybe it will eventually finish.  Over the last day or two, the iMac would hang 
for several minutes and then come back, so maybe the testing program hung for a 
while and then continued.  I'll let it run for a few more hours.
