Heatpipes and dunking in liquid (e.g. mineral oil) are options we've explored (with PCs), although we seem to be favoring pressure vessels at this point. Steve On Tue, Apr 16, 2013 at 2:34 AM, Jason Manley wrote: > I don't know of anyone who's actually

For closure purposes .. We resuscitated our roach with a USB wiggler, upgraded to the (not quite latest) tgtap and tcpborphserver in http://www.mail-archive.com/casper@lists.berkeley.edu/msg01370.html, and now the tut2 10GbE tutorial works (after removing the "name" argument in tgtap)! (We actual

Ugh. Dead roach. I ran "run newuboot" and started sending the file, but HyperTerminal failed with a "Did not receive response". I tried sending the file a second time and got the same response. Without other alternatives I then powered off the roach. Now I get nothing on the serial line when p

Hi, I'm trying to track down why our roach 10GbE is not transmitting. We have this roach configuration from Nov 2009 (in order to be compatible with another roach system - exception: our Uboot version is a bit different). Inte
