Would there by some way to pull the power instead of conventional shut down, and recover the contents of ram without loading the operating system upon the next start-up? I'm trying to recover files open on an unresponsive Ubuntu live cd.
Update:
I read the paper suggested by Alex and I think that's probably my best bet. Like Dan D said, you don't need liquid nitrogen, the paper itself suggests dust cleaner fluid in those cans to lower the temperature. I'll give it a try and post the results here. If anyone has any suggestions, please let me know.
From what I gathered from the paper, I lower the RAM's temperature to around -50 degrees before cutting power, cut power, boot a modified program supplied by the paper's authors from a USB stick, which then dumps the RAM's contents to the USB.
