Cut the cord about 20cm from the power supply, and fit a screw terminal, so the cord can be reassembled if needed. Yes, the XO will safely run direct from any 12V lead-acid storage battery. The battery will not permit the voltage to exceed what the XO can accept. (It isn't technically a step-down transformer, but a switch-mode power supply, but no matter.) -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
