I had to do this on an Ultra 10. While I don't remember the exact
details of the procedure, basically it was:
1. Pull the cover.
2. Power on the machine until the video starts, then (quickly and
carefully) pull the NVRAM chip to get control.
3. After the machine is halted, (carefully) reinstall the NVRAM and run
4. Power cycle.
I cringed when trying this on my Ultra 10, but it worked. Don't even
think about trying it unless you're willing to take responsibility for any
and all consequences. :-)
