(This seems to be the result of a very slow IPMI implementation; the default timeout of 3 seconds was clearly not long enough. The IPMI specification recommends "at least" 5 seconds, but that didn't work out either. The BIOS setup thing is also very slow when talking to the device.) > If you can convince Quanta to fix their BIOS that would be the best > result however. We're about to get four more of these things, so I hope to at least find out whether it's still broken (probably). There's also a checksum error, and when I flashed one system with a newer BIOS, that was still there too. -GAWollman
