Ahh, if you could, update it with info from ipmitool / ipmiutil. I was reluctant to add support based on reverse engineering. But if other tools have "official" interpretations from Supermicro, I'm more confident in the addition. > Yep, that's the code. ipmitool and a few others decode it too. > > > We have a *lot* of Supermicros so I can help with testing if needed - > but we don't get that much CRC errors though :) The one thing I'll need is product ID numbers (you can get from bmc- info) and the name of the product. This goes into the documentation and some of the code. Thanks, Al > So I guess we'd have to wait till one pops up.
