Will,

The short answer is nothing.

I have observed exactly the same error message on my system during the 
last week.

My story goes something like this. I repartioned my imac summer 2000 
system about 1 week ago, and went to reinstall netbsd-1-5-2. I received 
exactly the same error message. However, I had done nothing different to 
previous installation a few months earlier. I had in the previous week 
done the 4-1-9 firmware upgrade though, and I suspect that this upgrade 
has disturbed something in the cdrom controller, and produced a bug 
similar to the documented pciide problem. This means that cdrom cannot 
be accessed from netbsd while another device on the same bus is being 
used, such as the hard disc.

So, I created a hybrid cdrom using my copy of Toast, and booted from the 
hybrid cdrom, and then installed netbsd-1-5-2 manually bypassing sysint. 
This worked, albeit with a raised hassle factor. Even though the netbsd 
system is up and running again as per normal now, the cdrom is not 
operational.

This is definitely a work-around based upon my diagnosis of the problem, 
and I am relieved that someone else has encountered this problem.

Does anyone have any ideas, or insights into the cause or the ultimate 
cure for this problem?
