Today running ubuntu attempted to reset usb, but found no storage device and the wrong size of something or other. I panicked because I have an important job to do this afternoon, that essentially requires Scribus. I can think of two possible causes for the problem. Somewhat earlier I had been about to compose an e-mail through my e-mail service provider (gmail.hawaii.edu), looked away for a moment, and looked back to find a black screen. Still had the red lights shining in the X5000, but I couldn't get a flicker on the monitor.
It turned out to be a power outage. The computer was still on because of a backup power supply, but no wifi, and I don't usually plug the monitor into the backup.
When the power came back on, for some reason I ended up in OS4, rebooted, and that's when the "ubuntu" script failed me as described above.
Out of desperation I tried something I had no hope of working. I typed the above script into U-Boot but changed the "0:1" in the two fatload lines to "1:1" and here I am! Why? And what do I do now to make the original script work?
