Dear Chris et al, we have found the solution to this problem. It was actually "Crowbar" who was trying to downgrade the server's BIOS to an older version not compatible with this board. So, after we have reinstalled the correct BIOS version, using an external programmer, the server came back to life. In order to avoid such issues in the future, we have set to "false" the "Enable BIOS Update", in "BIOS" barclamp. Regards, Georgios
Dear all, first of all, since this is my first post in the community I salute everyone and hope to gain the maximum from our conversations.  I currently work in a lab environment to become familiar with the crowbar (for HADOOP).All servers are PowerEdge C6105. The problem (?). I've recently installed a crowbar admin node and I've added several nodes to it (reboot from PXE etc.). Due to various misconfigurations (on nodes), I've decided to "Delete" the nodes, thourgh Crowbar UI, in order to reboot the servers and start again the node procedure as according to the Crowbar Users' Guide "Completely removes all records of the node from the Crowbar/Chef database. If a node is deleted, it is rediscovered if it reboots.". But after that step, server seems not to boot at all. I don't even get POST messages. When I press power-on button I see nothing on the screen. Is there any "weird" mode that the server gets into and I have to recover it via an IPMI command or something? I've attached a VGA directly on the server, so there is no issue on web console.  Regards, gkasap
