Exactly correct, thank you Poul. The Soekris-supplied external brick (part number SBD212) was very ill. With no load, it was putting out 10V, with the Soekris connected (without disk) about 7.7V, and with the disk on, the power supply went gaga (that's a technical term for the voltage fluctuating down so much that I can't get a steady reading with a voltmeter). Replacing it with another 12V brick solved the problem. Thanks for the hint! The problem ended up much simpler than I had feared. -- Ralph Becker-Szendy ra...@lr.los-gatos.ca.us (408)395-1435 735 Sunset Ridge Road; Los Gatos, CA 95033 _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
